Summary table for comparative analysis between two numeric variables
stat_two_num.RdCreate a summary table with t.test: statistic, p-value and IC(95%).
Arguments
- df
A single data.frame
- grp_var
A character variable from a data.frame
- num_vars
One or more variables from a data.frame
Examples
n <- 20
set.seed(123);df <-
data.frame(
grp_var = sample(paste("group", letters[1:2]),size = n,replace = TRUE),
num_var1 = rnorm(n),
num_var2 = abs(rnorm(n))
)
stat_two_num(df,grp_var,c(num_var1,num_var2))
