I recently downloaded R for Windows, running on Win XP. I'm trying to create a perspective plot but not having any luck after reading the R manual and several examples found on the Internet.
I have a 100 x 100 matrix of Z data as a tab-delimited text file exported from Minitab. I read this in to R using read.delim; this seemed to go ok. I created X and Y using seq() to get 100 divisions for the X and Y axes. Again, everything looked good, when I typed X or Y I got a string of 100 numbers. However, when I try to do persp(x,y,z) I get an error something like: (list) cannot be coerced to double. I know the basic data (matrix of z values) is ok (no hidden non-numeric values) because Minitab will graph it just fine. Any suggestions on how to proceed? Thanks in advanced for your help. -- View this message in context: http://www.nabble.com/Beginner-Question-on-Persp%28%29-tf3174399.html#a8806483 Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
