report_nPctBin01: Frequency table for binary 0-1 variables

In angeloSdP/reportingTools: Tools for building report tables containing overall and per group summary statistics

Frequency table for binary 0-1 variables

Description

report_nPctBin01 builds a summary table with the frequency and percentage of times that one or more binary 0-1 variables takes the value 1. If a grouping variable is specified, absolute frequencies and percentages of 1's are computed in each group, and a chi-squared test is performed to test the difference of proportions of 1's between groups. If conditions for the validity of the chi-squared test are not met, a Fisher exact test is performed instead.

Usage

report_nPctBin01(data, summary_vars, groupVar = NULL, digits = 1, pvdigits = 4)

Arguments

data	data frame or tibble which contains the variables.
summary_vars	Binary variables which frequencies and percentages are to be computed
groupVar	Grouping variables.
digits	Number of decimal digits of the result.
pvdigits	Number of decimal digits in the p-value of chi-squared test.

Value

A table with the overall frequencies and percentages of 1's in each one of the required variables and, if a grouping variable is specified, the frequencies and percentages of 1's in each group as well as a chi-squared test for comparing proportions of 1's between groups.

Examples

 df <- data.frame(x=rbinom(90,1,0.3),y=rbinom(90,1,0.8), z=rbinom(90,1,0.5),
 g=sample(c("Yes","No"),90,replace=TRUE))
df %>%
report_nPctBin01(c(x,y,z))  # Overall summary of variables x, y and z
df %>%
report_nPctBin01(c(x,y,z), groupVar=g, digits=3)
