Regarding the flame, your might be interested in the following:
read.table(myfile, as.is=T) which will interpret character columns as character rather than factor and still reads in the numeric columns as numbers. You can also specify specific columns such as as.is=3:4 if you want columns 3 and 4 to be character but other character columns to be factors. --- Date: Mon, 15 Mar 2004 11:04:08 -0500 (EST) From: Tom Blackwell <[EMAIL PROTECTED]> To: Janet Gannon <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Subject: Re: [R] Simple numeric "as.is" question Janet - Try x2 <- as.numeric(as.character(x)) hist(x2) I'm not a Windows user, so I can't test this before sending. It might solve the problem, might not. (Flame !! : This is just ONE MORE example of the difficulties caused by the default behavior of read.table() to make things into factors. I sincerely wish the default were to preserve character data as character.) - tom blackwell - u michigan medical school - ann arbor - On Mon, 15 Mar 2004, Janet Gannon wrote: > I am reading a list of numbers from my clipboard, and have been > successful, except I can't make a histogram as R doesn't recognize my > variable as numeric.
