Hi Alfredo, I have not used SAS nor done a correspondence analysis in many years but to give R-help readers an idea of what you are doing, we probably need a short statement of the substantive problem that would lead to the SAS program: proc corresp data=table dim=2 outc=_coord; table Preference, Sex Age Time;
I believe that there are several packages in R that will do a correspondence analysis (For one see https://www.statmethods.net/advstats/ca.html). Have you checked out any of the packages? If so which one are you thinking of using? Next, we need to see some sample data. Have a look at these two links that may help you give us more information on the problem and what you are looking for. It is important to supply some sample data. It does not have to be much. The very best way to supply the sample data is to use the dput() function that you will find described in the links. http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example http://adv-r.had.co.nz/Reproducibility.html On Fri, 29 Mar 2019 at 17:35, jim holtman <jholt...@gmail.com> wrote: > > 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.
