Hi,
I'm not sure if the real English warning is the same. I translated it
from German. R came up with the following message:

I just got stuck with a quite simple question. I've just read in an
ASCII table from a plain text file with read.table(). It's a 1200x1200
table. R has assigned variables for each column: V1,V2,V3,V4,...
For small data sets
data <- read.table("data.txt");
data.matrix <- cbind(V1,V2,V3);
works.
Yes, contourplot() takes irregular spaced values, but you need a regular
grid to project the data on to.
grid <- expand.grid(x=x,y=y);
contourplot(z~x*y,grid,cuts=50);
This gives me a plot with little coloured areas around my datapoints only.
A better way for me was to
library(akima);
data.int
Hello,
I'm dealing with the following problem:
I have a table with x and y coordinates and corresponding values of
a mineral concentration, let's call it z.
Can someone provide me a short step-by-step manual for the steps
necessary to get a contour map?
