x.out = setx(z.out, age=mean)

My best guess is that the error occurs because the values for "gender" and "race.white" have a different length than "age" and "age2" Try something like: setx(z.out, age=age.sim, age2=age2.sim, gender=rep(0, length(age.sim)), race.white=rep(1, length(age.sim))) On Mar 1, 2012, at 11:06 PM, Rogério Barbosa wrote: Hey all, I get this error when I run setx: "Error in dta[complete.cases(mf), names(dta) %in% vars, drop = FALSE] : incorrect number of dimensions" I found some people with the same problem on internet - but apparently no one has worked it out.
