I would like to contribute in some way, I will look around for a project that's about my size. A few questions/comments about minor S-PLUS/R inconsistencies: 1) complex() in S-PLUS also takes optional arguments modulus and argument (instead of re and im): I just wrote a little wrapper program Complex _ function(modulus=1, argument=0) { complex(real=modulus*cos(argument),imag=modulus*sin(argument)) } but perhaps this change should be made in the C code itself (I would consider doing it myself as soon as I've gotten a little more familiar with the way the C code works). 2. In S-PLUS, if Z is a matrix, image(Z) works -- in R, you get a missing argument error and have to say image(z=Z); again, not a big deal and (presumably) fairly easy to fix. 3.. Any plans to implement acf(), etc.? (I may get around to writing my own.) 4. Any plans for 3-D graphics (persp() and friends)? This is a place where it would presumably be very easy to do better than S-PLUS (at least than release 3.1, which is what I'm using), where 3-D graphics are very clearly old and clunky. I guess a fair amount of thought should go into the design phase, though ... -- in future, should I bother sending comments like this (for which I don't really need help) to the help-list, or just to the R address?
