tableFunc: Format for printing frequency and percentages

In jbirstler/biostatrpts: Functions for UW-Biostatistics Report Creation

Description

Meant to be used in creating R matrix to be exported as a table

Usage

tableFunc(data, fvar, gvar = NULL, level = NULL, digits = 1)

Arguments

data	Data frame where nvar and gvar can be found
fvar	Character string of column in data of factor data
gvar	Character string of column in data of grouping data
level	Character string of level of fvar to be reported. If null then all levels are printed
digits	Number of decimals to be printed

Details

table(fvar,gvar) and 100*prop.table(table(fvar,gvar),2) are used to create N (%) for each level of fvar by gvar. If only 1 level is needed (i.e. Yes/No variable only needs Yes to be reported) then level can specify which level to print

Value

Returns a vector of strings of N (%) from table(fvar,gvar) with columns printed first. If gvar is NULL then N (%) of fvar is returned.
