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.

Bob



x, y, z
10, 0.1, 3

20,0.1,12
20,0.2,4
