Hi folks,
I have a small problem that I think someone out there might of already
run into.
i have a data matrix with 5 columns (i.e. data)
var <- 3
model <- lm(data[,1]~data[,2]+data[,var]
S-plus recognizes that var equals 3 so when the model is built it
includes the third column of the matrix "data", however, in the output it
maintains the var name in the final model so when I attempt to remove
this variable , i.e.
model <- drop1(model,~.-data[,3])
s-plus doesn't recognize the variable data[,3]. Due to the nature of the
routine that I am writing, I need S-plus to recognize that var = 3 in the
final model, so that I can refer to that variable as data[,3] later in
the program. I hope that this is clear. Thanks in advance.
Cheers,
Julian
