# Tables with labels in R

#### 2022-01-06

## Introduction

`expss` computes and displays tables with support for ‘SPSS’-style labels, multiple / nested banners, weights, multiple-response variables and significance testing. There are facilities for nice output of tables in ‘knitr’, R notebooks, ‘Shiny’ and ‘Jupyter’ notebooks. Proper methods for labelled variables add value labels support to base R functions and to some functions from other packages. Additionally, the package offers useful functions for data processing in marketing research / social surveys - popular data transformation functions from ‘SPSS’ Statistics and ‘Excel’ (‘RECODE’, ‘COUNT’, ‘COUNTIF’, ‘VLOOKUP’, etc.). Package is intended to help people to move data processing from ‘Excel’/‘SPSS’ to R. See examples below. You can get help about any function by typing `?function_name` in the R console.

## Installation

`expss` is on CRAN, so for installation you can print in the console `install.packages("expss")`.

## Cross-tablulation examples

We will use for demonstartion well-known `mtcars` dataset. Let’s start with adding labels to the dataset. Then we can continue with tables creation.

    library(expss)
    data(mtcars)
    mtcars = apply_labels(mtcars,
                          mpg = "Miles/(US) gallon",
                          cyl = "Number of cylinders",
                          disp = "Displacement (cu.in.)",
                          hp = "Gross horsepower",
                          drat = "Rear axle ratio",
                          wt = "Weight (1000 lbs)",
                          qsec = "1/4 mile time",
                          vs = "Engine",
                          vs = c("V-engine" = 0,
                                 "Straight engine" = 1),
                          am = "Transmission",
                          am = c("Automatic" = 0,
                                 "Manual"=1),
                          gear = "Number of forward gears",
                          carb = "Number of carburetors"
    )

For quick cross-tabulation there are `fre` and `cross` family of function. For simplicity we demonstrate here only `cross_cpct` which calculates column percent. Documentation for other functions, such as `cross_cases` for counts, `cross_rpct` for row percent, `cross_tpct` for table percent and `cross_fun` for custom summary functions can be seen by typing `?cross_cpct` and `?cross_fun` in the console.

    # 'cross_*' examples
    # just simple crosstabulation, similar to base R 'table' function

We have more sophisticated interface for table construction with `magrittr` piping. Table construction consists of at least of three functions chained with pipe operator: `%>%`. At first we need to specify variables for which statistics will be computed with `tab_cells`. Secondary, we calculate statistics with one of the `tab_stat_*` functions. And last, we finalize table creation with `tab_pivot`, e. g.: `dataset %>% tab_cells(variable) %>% tab_stat_cases() %>% tab_pivot()`. After that we can optionally sort table with `tab_sort_asc`, drop empty rows/columns with `drop_rc` and transpose with `tab_transpose`. Resulting table is just a `data.frame` so we can use usual R operations on it. Detailed documentation for table creation can be seen via `?tables`. For significance testing see `?significance`. Generally, tables automatically translated to HTML for output in knitr or Jupyter notebooks. However, if we want HTML output in the R notebooks or in the RStudio viewer we need to set options for that: `expss_output_rnotebook()` or `expss_output_viewer()`.

## Example of data processing with multiple-response variables

Here we use truncated dataset with data from product test of two samples of chocolate sweets. 150 respondents tested two kinds of sweets (codenames: VSX123 and SDF546). Sample was divided into two groups (cells) of 75 respondents in each group. In cell 1 product VSX123 was presented first and then SDF546. In cell 2 sweets were presented in reversed order. Questions about respondent impressions about first product are in the block A (and about second tested product in the block B). At the end of the questionnaire there was a question about the preferences between sweets.

List of variables:

- `id` Respondent Id
- `cell` First tested product (cell number)
- `s2a` Age
- `a1_1-a1_6` What did you like in these sweets? Multiple response. First tested product
- `a22` Overall quality. First tested product
- `b1_1-b1_6` What did you like in these sweets? Multiple response. Second tested product
- `b22` Overall quality. Second tested product
- `c1` Preferences

    data(product_test)

    w = product_test # shorter name to save some keystrokes

    # here we recode variables from first/second tested product to separate variables for each product according to their cells
    # 'h' variables - VSX123 sample, 'p' variables - 'SDF456' sample
    # also we recode preferences from first/second product to true names
    # for first cell there are no changes, for second cell we should exchange 1 and 2.
    w = w %>%

We can save labelled dataset as *.csv file with accompanying R code for labelling.

    write_labelled_csv(w, file  filename = "product_test.csv")

Or, we can save dataset as *.csv file with SPSS syntax to read data and apply labels.

    write_labelled_spss(w, file  filename = "product_test.csv")
