Can anybody of the architects of R enlighten me about the reasoning behind the selection of the IEEE 754 mode for the building of R, please? Special points of interest are: 1. The selection seems to be based on the availability of isnan() and finite(). Is this a common way to test for IEEE 754? 2. The C9x draft introduces isfinite() instead of finite() (and as I see, some systems, e.g. the

I want to report the progress of my attempts to get R running on HP-UX with gcc: Firstly, I could work around the PIC problem by leaving out all the lib stuff (I rebuilt gcc with --enable-share, but this (alone) did not help), e.g. the line gcc -shared -fPIC -o ctest.sl ansari.o fexact.o kendall.o ks.o prho.o swilk.o -L/usr/local/lib -lg2c -lm -L/lib/pa1.1 -L/usr/lib/pa1.1 -u main

I have a problem to understand the way gc_inhibit_torture is defined. In include/Defn.h it is declared as extern, using the __MAIN__ trick this leads to a definition in main/main.c. But in main/memory.c you define (and initialize) gc_inhibit_torture again: int gc_inhibit_torture = 1; /* gets set to zero after initialisations */ Then, in e.g. unix/system.c immediately at the beginning of

In Matlab or Octave I can evaluate (evalf) the content of a string. In R I have looked around in the docs, but have not found a way to do something equivalent (which is possible, I think). Can anybody give me a pointer? ============================================================================= Thomas Hoffmann, Institut fuer Halbleiter- und Mikrosystemtechnik, TU Dresden E-mail: hoffmann at

I try to fit reaction kinetic data to a given hypothetical model consisting of 3 ODEs. After some reading in Bates/Watts and the literature cited there (e.g. Jennrich/Bright) I looked in R for functions that support the use of the matrix exponential method. Until now I used for a similar (but simpler) problem the nls package and fitted against the the parameterized solution function. But this

After the overwhelming response to my last question (many thanks!), I cannot resist to ask the next maybe trivial question: All sources I have looked into tell me about building data frames by reading from files or by putting vectors of data ("column by column") together. Now I would like to create an (empty) data frame with "headings" for every column (column titles) and then

I tried to build R-1.1.1 on my HP-UX 10.20 box. For this I installed gcc 2.95.2 and built g77 (version 2.95.2 19991024 (release)). Making R runs to the point, where shared libs are linked. There it reports: make[4]: Entering directory `/disk4/hoffmann/Work/rwork/src/library/ctest/src' gcc -I../../../../include -I/usr/local/include -fPIC -g -O2 -c

gday R friends, I was wondering if anyone could help me with some graphics issues please. I'm processing R in batch on redhat6.2 with some graphics to be imported into msword on NT. For scaling within my doco I want some vector type graphics. win.metafile doesn't seem to be supported on redhat which gives me postscript. postscript is ideal but doesn't contain a preview so I

hi, all. I use R on a unix (linux) box and am quite happy with it. However, sometimes I need to create a graph that needs to be used with Microsoft Word or Powerpoint (ug). I can create a png or jpeg format picture, but the text look pretty crummy because jpeg is bitmapped. I can also create a PS/EPS version (my preference), but then it doesn't display properly in word or powerpoint (but it

It seems like a very common expectation that the following code would work: class boo { $me = "/something" file { $me: ensure => present } } class yay inherits boo { $me = "/something/else" } Yet, as many have found to their chagrin, it does not work. Should it? I believe I know how I could make this work: Create a single variable namespace for class

With some chagrin after spending a couple of hours trying to debug a script, I realized I had typed in something like ans<-optimx(start, myfn, mygr, lower<-lo, upper=up) that is, the "<-" rather than "=". The outcome on my machine was a non-obvious error several layers deep in the call stack. For info, optim() seems to stop much more quickly. The error is

I have a bunch of road warriors who I've set up with Xlite clients. Unfortunately the sound quality has been intermittent at best. Sometimes it's great other times completely unusable. When it's bad one usually hears harsh static when the other party speaks or their voice gets "clipped" to static if they speak too loudly. Many of these users have migrated to Skype ? much

I was hit by ugly crashes of R, when I tried to read big data sets ("volcano"). So I looked into the code and found the following in character.c (triggered by substr()): I assume that the helper function AllocBuffer() shall facilitate an economic memory management. But the use of realloc() in the else-branch does not conform to ANSI and may hit you with certain compilers. When called

Hi, I was wondering if someone had any thoughts as to why "preexec" doesn't fire when "msdfs proxy" is used?

Hello, on my work onli me work under Linux Fedora 10. Most we work with telnet and web-interface but for more comfort some of my collegs write program on delphi. This program good run and work under Windows xp, but doesn't work under my OS with wine 1.1.18. I have some chagrin because do little more work then other do =( That what I have, when run program in command page: Code: [Anton at

This is mostly a RFC [but *not* about the many extra packages, please..]: Noticing to my chagrin how my students work in a project, googling for R code and cut'n'pasting stuff together, accumulating this and that package on the way all just for simple daily time series (though with partly missing parts), using chron, zoo, lubridate, ... all for things that are very easy in base R *IF*

This is my first question to this list and possibly a bit dumb, but anyway: Can anybody tell me, where, e.g. in the "unix" reference release a DEFINITION of char * R_Home can be found? Via Defn.h the "extern" DECLARATION is everywhere, but when I derived a somewhat other main() program my linker complained about the missing definition. Thomas Hoffmann.
