hey, Dennis,
I applied your syntax into my data frame with different variable
names.
Specifically, I replaced y1 and y2, with ocbi and ocbo. I got the
following
error message. Could you please explain why would this happen? Again,
thanks!
for(i in 1:5){fm1<-as.formula(paste('ocbi',ms[i],sep='~')) fm2<-
as.formula(paste('ocbo',ms[i],sep'~'))
Error: unexpected string constant in:
"for(i in 1:5){fm1<-as.formula(paste('ocbi',ms[i],sep='~'))
When you get a message like that it is going to be a missing
<something>, usually right near the end of the presented string in the
error message,
,,, and in your case it is a missing "=" sign,
fm2<-as.formula(paste('ocbo',ms[i],sep'~'"
