Package GSS for interpolation in more than 2D?
Dear all, There has been some time since I asked about interpolation in higher (>2) dimensions, and I must admit I failed to write a function to do this myself the last time, but eventually ended up doing it in MATLAB. I tried to translate the MATLAB code, but MATLAB code is so much more opaque than R (S) code, so I failed that too, mainly because I could only get one MATLAB session, I would

Writing lgrindefs
Dear all, I'm writing a lgrind definition for R. Lgrind is a program to produce pretty program listings for inclusion in LaTeX documents. Does anybody here have any experience with lgrindefs?

Needed: Understading runif() output :-)
Dear all, I have been trying to understand what runif() is telling me. I am generating lots of numbers (billions and billions (wow, I''ve dreamed about saying that for many years... :-) ), for a distribution that has the following quantile function: 1 / (2 * sqrt(1 - p)) (that is, the distribution has a lower cutoff) As you can imagine, this has rather heavy upper tail. I was

Bus Error crash (PR#551)
Full_Name: Kjetil Kjernsmo Version: 1.0.1 OS: osf1 Submission from: (NULL) (129.240.28.227) Ouch, another obscure bug... I just had a bus error crash, with a core dump, a small one this time. Usual <URL:http://www.astro.uio.no/~kjetikj/tmp/core>. I had done a few simulations, and done a chisq.test() on them. These simulations also write about 190MB's to file, but I have no idea whether

R Documentation(s)
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

q() problem and more.
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

interp equivalent
Hi I'm looking to a function in R equivalent to S-PLUS' "interp". Is there any implementation in R? If not, is there any similar interpolation function such that at the data points the interpolated values concides with the data? Thanks in advance P.J.

Unix installation
I am trying to install R on a unix workstation (Sun-SPARC) but I am not sure which of the binaries to use. The only binaries available are for linux, nextstep, osf, and windows. Which one of them will work for a SUN sparc station?? Thanks. PS. I tried to compile the source code but it looks like I have a probelm with fortran. So, if I could install one of the binaries it would be a lot

Garbage Collecting
Dear all, Me and the Garbage Collector doesn't understand each other... I'm on R-1.0.1 (I have requested an upgrade to the right local people), an osf1 system with an alphaev6 CPU. I have fair amounts of memory to use, but it seems to be used up pretty fast nevertheless. I'm now trying to see what the garbage collector does, I have inserted a gc(v=T) call at a spot in my code.
