I'm trying to use 'dropterm' (from MASS) in a function along the lines
run <- function(dat){
fit <- (something)(Y ~ (something), data = dat)
lr <- dropterm(fit, test = "Chisq")
return(fit, lr)
}
but running 'run' I get (those scoping rules again...?)
Error in terms.formula(formula, special, data = data) :
Object "dat" not found
This works fine at the command line. Can I send 'dat' to 'dropterm'
somehow, or what should I do?
Thankful for any suggestion, including reading certain books!
