Structuring data for Correspondence Analysis
I am not familiar with SAS, so what did you want your output to look like. There is the 'table' function that might do the job and then there is always 'dplyr' which can do the hard stuff. So we need more information on what you want.

Hi, I am very new to r and need help from you to do a correspondence
analysis because I don't know how to structure the following data:
Thank you.

library(ca,lib.loc=folder)
table <- read.csv(file="C:\\Temp\\Survey_Data.csv", header=TRUE, sep=",")
head (table, n=20)
Preference Sex Age Time
1 News/Info/Talk M 25-30 06-09
2 Classical F >35 09-12
3 Rock and Top 40 F 21-25 12-13
4 Jazz M >35 13-16
5 News/Info/Talk F 25-30 16-18
6 Don't listen F 30-35 18-20
...
19 Rock and Top 40 M 25-30 16-18
20 Easy Listening F >35 18-20
In SAS I would simply do this:
proc corresp data=table dim=2 outc=_coord;
table Preference, Sex Age Time;
run;
I don't know how convert in R a data frame to a frequency table to execute
properly this function:
ca <- ca(<frequency table>, graph=FALSE)
