I'm no expert in R but I think that read.table simply will not start a variable with a numeric. If you really want the names to be as listed below you can assign them after import by using :
names(mydata) <- c(name, "20_1_TT_Z_e4" "20_2_TT_Z_e4") name is a factor as far as I can see because that is the default in your R-profile See http://finzi.psych.upenn.edu/R/Rhelp02a/archive/98227.html for more details name's mode is numeric because the underlying form of a factor is numeric. do str(mydata) for a bit more information ----- Original Message ---- From: Neuer Arkadasch <[EMAIL PROTECTED]> To: Neuer Arkadasch <[EMAIL PROTECTED]>; [EMAIL PROTECTED] Sent: Friday, October 19, 2007 9:30:38 AM Subject: Re: [R] header Maybe I had to write that the original data what I read are name 20_1_TT_Z_e4 20_2_TT_Z_e4 A1 102 22 A2 103 21 A3 107 20 Thatk you!

Is it possbile to have it as 20_1_TT_Z_e4 ? --------------------------------- Ihre erste Baustelle?
