# 1 Introduction

This package `clinUtils` contains functionalities to facilitate the analysis of clinical datasets in R.

    library(clinUtils)

    # packages required for the examples in the vignette
    library(ggplot2)
    library(pander)
    library(htmltools)
    library(plyr)

Please note that the interactive outputs (table/visualization) in this vignette are only included if Pandoc is available (pre-requisite for R Markdown).

# 2 Data pre-processing

## 2.1 Data import

The `haven` R package enables to load SAS datasets in `sas7bdat` and `xpt` formats.

The function `loadDataADaMSDTM` is a wrapper to import multiple SAS datasets in `sas7bdat` or `xpt` format at once. It returns a list of dataset (once by domain). The variable labels are combined across datasets and available in a dedicated attribute.

    pathExampleDatasets <- list.files(
        path = system.file("extdata", "cdiscpilot01", "SDTM", package = "clinUtils"),
        pattern = "*.xpt",
        full.names = TRUE
    )

    data <- loadDataADaMSDTM(files = pathExampleDatasets)
    # A list is returned, each separated file is accessible via data$[fileName]
    pander(head(data$DM, 2))

## 2.3 Variable labels

Typical data stored in SAS contains the label for each variable available in the dataset.

The function `getLabelVar` extracts the label for the specified variable(s), ensuring that the variable code is used if no label is specified.

    # variable label is extracted from 'labelVars'
    getLabelVar(var = "AEDECOD", labelVars = labelVars)

    ##                   AEDECOD
    ## "Dictionary-Derived Term"

This function also supports extraction of variable labels from the ‘label’ attribute of the column, as in the tibble as returned by the `read_sas`/`read_xpt` functions from the `haven` package.

## 2.4 Get parameter label from its parameter code

In typical basic CDISC dataset (a.k.a BDS: Basic Data Structure), as laboratory, vital signs datasets, variables are available to store parameter and parameter code (`PARAM`/`PARAMCD` in ADaM).

The function `getLabelParamcd` get the label from specific parameter(s) code.

Variables with parameter name and code are based by default on standard ADaM CDISC parameter variables (`PARAM`/`PARAMCD`).

    # For ADaM dataset
    getLabelParamcd(paramcd = "CHOL", data = dataADaM$ADLB)

    ##                   CHOL
    ## "Cholesterol (mmol/L)"

    getLabelParamcd(paramcd = "BILI", data = dataADaM$ADLB)

    ##                 BILI
    ## "Bilirubin (umol/L)"

    # For SDTM dataset
    getLabelParamcd(paramcd = "CHOL", data = dataSDTM$LB, paramcdVar = "LBTESTCD", paramVar = "LBTEST")

    ##          CHOL
    ## "Cholesterol"

    getLabelParamcd(paramcd = "BILI", data = dataSDTM$LB, paramcdVar = "LBTESTCD", paramVar = "LBTEST")

    ##        BILI
    ## "Bilirubin"

# 3 Visualizations

## 3.1 Palette for CDISC variables

Palette for typical CDISC-variable(s) are available in the package.

### 3.1.1 Normal reference range indicators

Meaningful colors and symbols for a Normal Reference Range Indicator CDISC variable (`-NRIND`) are extracted via the `colorPaletteNRIND` and `shapePaletteNRIND` respectively:

The `getPaletteCDISC` function extracts such palette for a specified variable.

This retains only the categories available in the variable, and ensures that extra symbols are extracted in case non standard categories are available in the data.

    dataPlot <- subset(dataSDTM$LB, LBTEST == "Leukocytes")

    colorPalette <- getPaletteCDISC(x = dataPlot$LBNRIND, var = "NRIND", type = "color")
    print(colorPalette)

        scale_fill_manual(values = colorPalette, limits = names(colorPalette)) +
        scale_shape_manual(values = shapePalette, limits = names(colorPalette))

## 3.2 Get default palettes

Default palettes for visualizations are included in the package.

Palettes can be extracted based on a variable, or number of elements.

These packages are included for consistency across the entire suite of R packages.

    dataPlot <- subset(dataADaM$ADLB, PARAMCD == "CHOL")

    # extract palettes
    colorPalette <- getColorPalette(x = dataPlot$USUBJID)
    shapePalette <- getShapePalette(x = dataPlot$USUBJID)
    linetypePalette <- getLinetypePalette(x = dataPlot$USUBJID)

    # create the plot
    ggplot(data = dataPlot, aes(x = ADY, y = CHG, color = USUBJID)) +
        geom_point(aes(shape = USUBJID)) +
        geom_line(aes(linetype = USUBJID, group = USUBJID)) +
        scale_color_manual(values = colorPalette) +
        scale_shape_manual(values = shapePalette) +
        scale_linetype_manual(values = linetypePalette) +
        labs(x = "Relative day", y = "Change from baseline",
            title = "Profile plot of cholesterol change from baseline")

    ## Warning: Removed 7 rows containing missing values (geom_point).

    ## Warning: Removed 7 row(s) containing missing values (geom_path).

Custom palettes can be specified via the `palette` parameter.

# 4 Tables

## 4.1 Rounding

In R, numbers are by default rounded to the even digit for rounding off a 5.

Numbers can be rounded based on the ‘rounding up’ strategy for rounding off a 5 with `roundHalfUp` & `roundHalfUpTextFormat`. This is useful when statistics created with the `SAS` software should be reproduced in R.

    # round up
    roundHalfUp(c(0.45, 0.55), 1)

    ## [1] 0.5 0.6

    # versus R default:
    round(c(0.45, 0.55), 1)

    ## [1] 0.4 0.6

## 4.2 Display data in an interactive table

The `getClinDT` function is an utility function, based on the the DT package, with sensitive default settings and extra common functionalities of interest for data in clinical trials, as listing or summary tables of descriptive statistics.

There are built-in functionalities to expand row variable(s) to display patient-specific information or include bar visualization.

    dataTEAE <- subset(dataADaM$ADAE, SAFFL == "Y" & TRTEMFL == "Y")

    # set column names to labels
    labelVarsTEAE <- getLabelVar(
        var = colnames(dataTEAE),
        labelVars = labelVarsADaM
    )
    colnamesTEAE <- setNames(names(labelVarsTEAE), labelVarsTEAE)

    dataTEAE <- dataTEAE[order(dataTEAE$AESOC), ]

    getClinDT(
        dataTEAE,
        colnames = colnamesTEAE,
        rowGroupVar = c("AESOC"),
        barVar = "AGE",
        barRange = c(0, 100),
        caption = "Listing of treatment-emergent adverse events on the safety analysis set"
    )

## 4.3 Comparison of tables

In clinical trials, datasets are typically delivered in successive batches, depending on the patient recruitment and the different milestones of the study.

The changes between successive data deliveries can be compared with the `compareTables` function.

    # Build example dataset with treatment-emergent adverse events
    # of multiple batches

    varsListing <- c("USUBJID", "AESOC", "AEDECOD", "ASTDT", "AESEV", "AEOUT")
    dataTEAEListing <- dataTEAE[, varsListing]

    # simulate removal of observations in new batch
    dataTEAENew <- dataTEAE[-sample.int(n = nrow(dataTEAEListing), size = 3), ]

    # simulate addition of observations in new batch
    dataTEAEOld <- dataTEAE[-sample.int(n = nrow(dataTEAEListing), size = 3), ]

    # simulate change of observations
    dataTEAEOld[seq_len(2), "AESEV"] <- "SEVERE"

    refVars <- c("USUBJID", "AESOC", "AEDECOD", "ASTDT")
    tableComparison <- compareTables(
        newData = dataTEAENew,
        oldData = dataTEAEOld,
        referenceVars = refVars,
        changeableVars = setdiff(colnames(dataTEAEListing), refVars),
        # parameters passed to datatable
        colnames = setNames(names(labelVarsADaM), labelVarsADaM)
    )

The new, old datasets with change information, or the difference between datasets are extracted. See documentation of `outputType` parameter for further details.

The table below highlight the differences between the datasets in an interactive table.

# 5 Reporting

## 5.1 Include list of objects in a Rmarkdown document

Dedicated functions: `knitPrintListPlots` and `knitPrintListObjects` are available to include a list of plots/objects in a `Rmarkdown` document, enabling to specify any (knitr) chunk options and title header for each object.

This function inserts each object in a separated code chunk, such as independent option (as figure dimensions) can be specified for each object.

Please note that this function should be used within a chunk having the option: `results = 'asis'`.

### 5.1.1 Static visualizations (`ggplot2`)

For example, by default in knitr the options to specify figure dimensions should be the same for all plots generated from the same chunk (`fig.height`/`fig.width`).

Plots can be included with different specified dimension with: `knitPrintListPlots`.

    dataLB <- subset(dataSDTM$LB,
        LBTESTCD %in% c("ALB", "ALT", "CHOL", "HCT", "KETONES", "PH")
    )
    dataLB$ACTARM <- dataSDTM$DM$ACTARM[match(dataLB$USUBJID, dataSDTM$DM$USUBJID)]

    # create plots:
    listPlotsLB <- plyr::dlply(dataLB, "LBCAT", function(data)
          ggplot(data = data) +
              geom_histogram(aes(fill = LBNRIND, x = ACTARM), stat = "count", position = "dodge") +
              facet_wrap(~LBTEST) +
              theme(axis.text.x = element_text(angle = -45, hjust = 0))
    )
    # n2mfrow: extract default dimensions for a specified number of plots
    figDim <- plyr::dlply(dataLB, "LBCAT", function(data)
          n2mfrow(length(unique(data$LBTESTCD)))
    )
    knitPrintListPlots(
        plotsList = listPlotsLB,
        generalLabel = "lab-hist-static",
        type = "ggplot2",
        # set caption for each figure
        fig.cap = paste("Barplot of", tolower(names(listPlotsLB)), "measurements"),
        # specify different dimensions
        fig.width = sapply(figDim, "[[", 1) * 2 + 1, # 3 in for each plot + 1 in for the legend
        fig.height = sapply(figDim, "[[", 2) * 2 + 2, # 3 in for each plot + 2 for x-axis labels
        # include title before each visualization
        titles = simpleCap(tolower(names(listPlotsLB))),
        titleLevel = 4
    )

#### 5.1.1.1 Chemistry

Barplot of chemistry measurements

#### 5.1.1.2 Hematology

Barplot of hematology measurements

#### 5.1.1.3 Urinalysis

Barplot of urinalysis measurements

### 5.1.2 Interactive visualizations (`plotly`)

A list of interactive figures is created with the `plotly` package:

    library(plotly)
    listPlotsInteractiveLB <- sapply(listPlotsLB, function(ggplot)
          ggplotly(ggplot) %>% partial_bundle()
        , simplify = FALSE)

#### 5.1.2.1 `htmltools::tagList`

A list of interactive figures can be included within a Rmarkdown document with the `tagList` function of the `htmltools` package.

    tagListArgs <- mapply(list,
        # section header
        lapply(names(listPlotsInteractiveLB), htmltools::h4),
        # interactive plots
        listPlotsInteractiveLB,
        SIMPLIFY = FALSE
    )
    tagListArgs <- unlist(tagListArgs, recursive = FALSE)
    do.call(htmltools::tagList, tagListArgs)

#### CHEMISTRY

#### HEMATOLOGY

#### URINALYSIS

#### 5.1.2.2 Inclusion in a separated chunk

The function `knitPrintListPlots` with the `type` set to ‘plotly’ enables to include additionally e.g. a caption or a title.

    knitPrintListPlots(
        plotsList = listPlotsInteractiveLB,
        generalLabel = "lab-hist-interactive",
        type = "plotly",
        # include title before each visualization
        titles = simpleCap(tolower(names(listPlotsInteractiveLB))),
        titleLevel = 5
    )

##### 5.1.2.2.1 Chemistry

##### 5.1.2.2.2 Hematology

##### 5.1.2.2.3 Urinalysis

### 5.1.3 Tables (`flextable`)

The `flextable` package enables to create highly customizable tables for Word/PowerPoint format (among others).

The function `knitPrintListObjects` enables to include a list of `flextable` objects within a single chunk.

Please note that the following chunk option should be used: `results = 'asis'`.

    library(flextable)
    listFtLB <- plyr::dlply(dataLB, "LBCAT", function(dataParcat){
          flextable::flextable(data = head(dataParcat))
        })

    knitPrintListObjects(
        xList = listFtLB,
        generalLabel = "lab-listing-ft",
        titles = simpleCap(tolower(names(listFtLB))),
        # different alignment for each table
        ft.align = c("center", "right", "left"),
        titleLevel = 4
    )

#### 5.1.3.1 Chemistry

#### 5.1.3.2 Hematology

#### 5.1.3.3 Urinalysis

Please note that the table alignment option is more visible in a Word output format.
