..., what am I getting...? So, I went on to thinking that > outer(10, 1:10, rpois) would do the trick, but no.... Again, what am I getting? So, is there a simple way of doing this...? If not, would it be reasonable for me to request this as a feature in future releases?

Hi Rers, W/o trying to make a long story short (I hope you read that correctly), I have been working on a nice little R function ... Somewhere along the line I got an error that refers to a max function in my function (I think this is a vector vs. scalar issue): Error in max(..., na.rm = na.rm) : invalid "mode" of argument If that's not bad enough, even when I q() R and say

Also, I'd like to tune the palette so that the break between green and red happens at a value of e.g. 0.05. How would I do that?

Dear all, I am interested by the various messages sent to the r-help mailing list these last few days about documentation on R. Yet, there are a lot of issues actually open on this topic, and it is not clear to me what is the "urgent need for documentation" on R. R comes with the 'Introduction to R' by Venables et al. I recommend the colleagues and students in my lab who are

...understood the docs for convolve correctly, it only works in 1D (and I have tried to convolve, it didn't look good). So, I wondered if anybody have implemented 2D convolution in R, or have any good advices to share (beyond having a look at mvfft), before I go hacking?
