wrong data interpretation in R
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. -- View this message in context: http://r.789695.n4.nabble.com/wrong- data-interpretation-in-R-tp4650849.html Sent from the R help mailing list archive at Nabble.com.
