Create frequency tables for multiple factor columns in R

Question

I am a novice in R. I am compiling a separate manual on the syntax for the common functions/features for my work. My sample dataframe as follows:

x.sample &l         


        

Answer 1

You were nearly there. Just one small change in your function would have got you there. The x in function(x) ... needs to be passed through to the table() call:

levs <- c("Not Impt at all", "Somewhat Impt", "Neutral", "Impt", "Very Impt")
sapply(x.sample, function(x) table(factor(x, levels=levs, ordered=TRUE)))

A little re-jig of the code might make it a bit easier to read too:

sapply(lapply(x.sample,factor,levels=levs,ordered=TRUE), table)

#                Q9_A Q9_B Q9_C
#Not Impt at all    3    4    4
#Somewhat Impt      0    0    0
#Neutral            0    0    0
#Impt               1    0    0
#Very Impt          6    6    6
