Hello, Listers
I'm trying to run blloean logit model with R.
My code is:
> library(boolean)
> library(foreign)
> pr <- read.dta ("prcore1.dta")
> bp <- boolprep ("(a&b)|c", "cwt", a="O1", b="t", c="DM2
> + ah + md + con + n3 + rel + slo + pyrs
> + sp1 + sp2 + spl3")
> answer <- boolean (bp, link = "logit", method = "nlm")
But I got an error message here as follows:
Error in eval(expr, envir, enclos) : object "cwt" not found
"cwt" is my D.V. and I made sure that R read the data correctly.
It might be a stupid question.But, since I'm a very very beginner of
R, I don't know what's wrong.
I tried to figure out this with the manual, but I can't get any answer.
Could you anyone help me out?
Thank you very much in advance.
Best,
Charlie
