Suppose your data is in image.txt, space delimited (one or more spaces),
then you could use:
myimage -
as.matrix(read.table('image.txt',skip=0,header=FALSE,sep=,strip.white=TRUE))to

image(myimage)
to get contours: contour(myimage)
etc.

Dear,
I have XYZ data available in a MySQL database. I get it out, can plot
the data with the plot() function, load it into a geoR datastructure.
But what I actually would like to do is a simple contouring of the data
based on a no Kriging interpolation such as TIN based.
I know the first

Dear,

Error in vector(double, length) : cannot allocate vector of length 79998
We can read the file without any problem with read.table, but trying to

Dear,
I'm looking for some examples on OO programming in R. I have the
programming manual with explanation on UseMethod and NextMethod but I
miss some practical examples to get me going (I hope). I searched the
web but could not find a good independent tutorial on this.
Any suggestions are
