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

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

Dear R Core Team, I'm wondering whether it is useful that every package should allow for help(PackageName), giving some general information about the package (more/nicer than library(help=PackageName)). This man page may include some mathematical or statistical background, or contain a guideline for the package. Cheers, Martin -- Martin Schlather email:

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 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

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.)

I am attempting to create a simple line chart graphing three columns from a soffice-calc spreadsheet. I expect it to take the leftmost column as the X-Axis, plotting the others on the Y-Axis, but it always creates an X-Axis of the row number in the columns, and the first column amongst the data. I have tried this on OpenOffice.org 3.2.0, NeoOffice(R) 3.0.2 Patch 2, iWork Pages, and Excel 12.2.4

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.

Professor Ripley commented on LAPACK error codes: https://stat.ethz.ch/pipermail/r-help/2007-March/127702.html and says "Internal LAPACK errors are usually problems with arithmetic accuracy, and as such are compiler- and CPU-specific." Is there a listing for the error codes from Lapack routine 'dsyevr'? Especially I am interested about the meaning and handling of error codes 1

Dear all, I am trying to use the C code for "integrate" function ( that calls Rdqagi and Rdqags) so that I can integrate a function defined in C, instead of passing from R. Is there a way for doing this? My unsuccessful attempt: I looked into the files (including integrate.c, Applic.h) and 1. modified the definition of "integr_fn" by droping the environment

Hi, I get an "Conditional jump or move depends on uninitialised value(s)" from valgrind when using 'solve' in combination with some simple C-code.

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

For nested function calls it appears that a combination of environment() and '<<-' will also work: f1 <- function() { x <- rep(NA,4) # Object to be modified by function f2 environment(f2) <- sys.frame(1) # Make f1's environment available to f2 f2(2) # Changes 2nd element of x print(x) } f2 <- function(i) { #

Hello there I'm writing some c-code to solve a numerically tough problem for me in R. Looking in Lapack.h, i find the following line F77_NAME(dgesvx)(const int* fact, const char* trans, const int* n, and I believe that "fact" should've been char instead of int, i.e. F77_NAME(dgesvx)(const char* fact, const char* trans, const int* n, My reasoning: In the R-source:
