hi: I have a y vector and an x data frame. is it possible to use the standard linear regression (lm, summary.lm) without having to construct a formula, i.e., all x variables should be used.
x <- data.frame( rnorm(10), rnorm(10) ); # <-- well, this would really be read from a file
y <- rnorm(10); # ok, also read from the file.
lm (y ~ x); # this is sort of what I want to do, but of course, it is not.
thanks for any tips. regards, /iaw
