I'm running a logit model using the zelig package in R:
z.out <- zelig(trade961a ~ age962 + education962 + personal962 + economy962 + partisan962 + employment962 + union962 + home962 + market962 + race962 + income962, data=data96, model="logit") The dependent variable, trade961a, is a dichotomous factor variable. All other variables are numeric. I am interested in personal962, which is: > str(personal962) num [1:1714] 3 3 1 1 1 2 3 2 2 1 ... so I run the following to simulate the probability of supporting international trade when personal962 is 1 (better): x.out <- setx(z.out, personal962=1) I get the following error message: #Error in dta[complete.cases(mf), names(dta) %in% vars, drop = FALSE] : # incorrect number of dimensions Any ideas on what I'm doing wrong?
