[Answering to the threads question] For those who use Gnome's gedit, there is now RGedit: http://sourceforge.net/projects/rgedit Apologies if this was already posted, Nikos
Thanks to all for the replies. I'll post back here when I get things working (...in a couple of days). Nikos

Greets (again) :-) I finally ran mrpp tests. I think all is fine but one very important issue: I have no idea how to export/save an "mrpp" object. Tried anything I know and searched the archives but found nothing. Any...

Hi R-specialists! I would like to draw some hyperbolic (iso-)lines of a cost function in a bi-dimensional space ( =shapes of a cost function ), based on (the general form): C(x) = c1*Ce + c2*Oe + c3*{ 1 - [ (1...

Greets to the list! I am aware that this topic has been discussed several times. And I've read quite some related posts [1]. Yet, can't seem to give a solution to my problem. I have 6 data frames...
