Hi, I have problems when calling fft_factor and fft_work directly in my C-code. Martin Maechler already told me that I should not do this -- anyway, the code works fine if the length of the vector is a multiple of 2,3,5. If the length of the vector has different form I get, in some cases, a segmentation fault when work and iwork are freed (I use C's malloc to allocate memory for work and

Hi, I have attached a larger Rd file that causes an error when compiled by R CMD Rdconv -t txt xswms2d.Rd (for example). If the size is reduced the error vanishes, see the lines 230 and 527 in the file. I could not find an error within my text and so my guess is that there is some buffer overflow within the compiler. If it is me who has caused the error please let me know -- and many

Martin Maechler asked me to restate my problem. Compiling the file (slightly modified w.r.t. the formerly attached file) that can be found at http://www.geo.uni-bayreuth.de/~martin/filetransfer/xswms2d.Rd terminates with the error message ******* Syntax error: mismatched or missing brackets in /----- ..... \----- when compiled by R CMD Rdconv -t txt xswms2d.Rd However, the file does

Dear all, (sorry I got the wrong button for subscribing a minute ago) At the moment I'm writing on a package for random field simulation that I'd like to make publically availabe in near future. To this end I've asked Martin Maechler to have a look at my R-code. He was very surprised about how I perform the ".C"-calls, and encouraged me to make this request for comments.

Hi, The help for `assign' says In all the assignment operator expressions, `x' can be a name or an expression defining a part of an object to be replaced (e.g., `z[[1]]'). The name does not need to be quoted, though it can be. So I would expect that by a<-1:4 assign("a[1]",2) the first component of a gets the value 2, but the object "a[1]" is

Dear all, Paulo Ribeiro, p.ribeiro@lancaster.ac.uk, and myself noticed that R sometimes breaks down with a segmentation fault of (at least for us) unknown course. (We've read #411 and #671 in the bug report on "optim" -- the problem described there sounds familiar; but we have not found any hint on a segmentation fault.) Please find at the very end of this email the file

Dear R-devel During the last half a year I have several times encountered the following problem with optim() when using method= "L-BFGS-B". The function return a value which is clearly not the maximum (seen from printing the value each time the function is called). Some output is shown below. A few things I have observed (as I remember it): a. The problem seems to occur when the

Hi, I've seen that some packages use .packageName internally to infer their own name. Is that officially supported? I could not find it documented anywhere. There's utils::packageName(), which internally looks for .packageName. However, if the latter is not found, it may return NULL whereas an error would be more appropriate if a package name is expected. Using .packageName would give

That's not too surprising, since R is now in /usr/lib/R, but what is confusing me is that R CMD INSTALL -l /path/to/library

Dear R community I currently try to get post hoc multiple comparisons with the package multcomp from a cox mixed-effects model, where the survival is explained by two variables (cover with levels: nocover and cover; treatment with levels: tx, uv, meta), whose interaction is significant. I read Hothorn, T. 2011: Additional multcomp Examples and there is an example involving a two-way ANOVA with

Hi, Please see the email exchanges below. I am having trouble generating output that is large enough for our needs, specifically when using the GaussRF function. However, when I wrote Dr. Schlather (the author of the GaussRF function), he indicated that there is also a limit imposed by R itself. Is this something that we can overcome? Thank you very much for any assistance you may provde.

Hello, after some discussions with Martin Maechler and Josef Leydold (WU Wien), we have felt the need for some package that should allow for an object-orientated approach to distributions. Our small group at Bayreuth now has developed a package "distr" which tries to fill this gap, implementing distributions by means of S4--classes. A mother class "Distribution" is
