freqTable: Generate a frequency table

In c-hill-mdrc/QCmemo: PSE QC Memo Helper Functions

Description

The function freqTable is somewhat analagous to PROC FREQ in SAS. The functionality is slightly different and more limited, but the results are aesthetically similar.

Usage

freqTable(
  inputds,
  variables,
  varnames = variables,
  n = TRUE,
  percent = TRUE,
  perc_digits = 1,
  bg = "aliceblue"
)

Arguments

inputds	A dataset with one row per unit (i.e. a Step 2 dataset).
variables	A vector of names indicating the variables you would like to be cross-tabulated.
varnames	A named list giving key-value pairs for how you would like the variables to be labeled on the table.
n	Logical. Should frequencies be displayed?
percent	Logical. Should percents be displayed?
perc_digits	A number indicating how many decimal places should be displayed for the percentages.
bg	The background color for the columns containing the calculated statistics. Can be given as either a name (e.g. "dodgerblue4") or using the rgb function.

Value

A flextable object.

Examples

# Simple cross-tabulation using default options
freqTable(inputds    = mtcars,
          variables  = c('cyl', 'gear', 'carb'))

# Using options to customize table further
freqTable(inputds    = mtcars,
          variables  = c('cyl', 'gear', 'carb'),
          varnames   = list(cyl = 'Cylinders', gear = 'Forward gears', carb = 'Carburetors'),
          n          = FALSE,
          perc_digits = 0,
          bg         = rgb(.2, .1, .2, .3))
