I'm having problems with this line of code:

d[x] is what is giving trouble here, but I don't know exactly how to
solve it. What I'm trying to do is to create a

How does d look like?
Probably d[,cls] and d[,x] instead of d[cls] and d[x]
d - data.frame(x1 = rnorm(100), x2 = rnorm(100), x3 = rnorm(100), cls =
rnorm(100))
dd - subset(d, sel=-cls)
lapply(paste(lm(cls ~, names(dd), ,data=d)), function(x)
eval(parse(text=x)))
