My R has been installed on a Ubuntu linux computer in Germany. The error
messages I get are in German, for example:

I would like those to be displayed in English, for pasting them into google.

I'm trying to create an image file with the results of a regression

Can I create a plot window with just this line in it? I tried playing
around with plot.new() or dev.new(), but didn't really find something

I figured out that if I use "x <- matrix(x,ncol=2)", instead of

Hi all,
Is there any one that would give an explanation on the abbreviation SEXP

I'm trying to write a function to determine the euclidean distance
