Robert -- it may be that some of your factor variables cannot be
coerced to numeric because they have non-numeric elements.
This is why we ask for a reproducible example when posting. I
suspect just a few lines from the data frame would tell the story.

Hi,
maybe somebody would be kind enough to help a bloody and
unprofessional
beginner like me (and I hope I did not overlook the answer to my
question on
the website). I've imported a csv data frame into R, but I can't run a
regression because R interprets 4 out of 5 variables as factors
(rather than
numeric vectors). I tried the as.numeric() command, but R says it
is invalid
to change the storage mode of a factor. Is there any way to change
the mode
of a factor into numeric.
I am very grateful for help. Thank you very much, Robert.
