Please **READ** ?contour. x and y are the location of grid lines, z must be a matrix. Your data are **not** of that form.

Hello list, I'm new to R and I have a problem :-) Below is what my data file that looks like. I tried to import and contour this data by doing this: cv_data <- read.table("cv_data.csv",sep=",",header=TRUE) attach(cv_data) contour(x,y,z) I get the error "Error in contour.default(x,y,z) : increasing 'x', and 'y' values expected" I can see that y is not increasing, but I don't know how to get this to work. Thanks in advance for any help.
