loading compiled C++ code as shared library
Dear People,
Over the last few days I've been writing C++ to compile as a shared
library (previously I have always used C). Not entirely to my surprise, I
am getting errors. Specifically, when I try to load the shared library, I
get
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library

PKG_CFLAGS/CFLAGS and PKG_CXXFLAGS/CXXFLAGS
Why is it that R places CFLAGS after PKG_CFLAGS and not before when
compiling a package (e.g. through R CMD build pkg)? This can be
problematic if, for instance, you want to use -O3, but -O2 is in
R_HOME/etc/Makeconf. If -O2 (in CFLAGS) appears after -O3 (in
PKG_CFLAGS), you are left with what you didn't want: -O2.
In R-exts, it says that "Flags which are set in file etc/Makeconf

choosing g/g++ compiler executable in R CMD SHLIB
Dear People,
After considerable effort, I managed to install gcc-3.0 on my Debian
system. However, Debian keeps gcc-2.95 around as the default compiler, and
gcc, g++ point to the 2.95 version. The 3.0 versions need to be explicitly
invoked as gcc-3.0, g++-3.0 etc. How can I get R CMD SHLIB to invoke
gcc-3.0 instead of gcc and g++-3.0 instead of g++? I would like this to be
done by default but

How to ensure -O3 on Win64
Hi,
Similar questions have come up before on the list and elsewhere but I
haven't found a solution yet.
winbuilder's install.out shows data.table's .c files compiled with -O3
on Win32 but -O2 on Win64. The same happens on R-Forge. I gather that
some packages don't work with -O3 so the default is -O2.
I've tried this in data.table's Makevars (entire contents) :

passing arguments to R CMD SHLIB
Dear People,
I want to run gcc with optimisation turned on (-O2), and with -Wall (all
warnings) enabled, when using R CMD SHLIB. When I do make, which is
R CMD SHLIB -Wall -O2 cftp.c mcmc.c latticefn.c -lm
in this case, I get
faheem ~/research/cftp>make
R CMD SHLIB -Wall -O2 cftp.c mcmc.c latticefn.c -lm

R CMD SHLIB uses foo.c instead of foo.cc if both are present (PR#2644)
Full_Name: Faheem Mitha
Version: 1.6.2
OS: Debian GNU/Linux
Submission from: (NULL) (209.42.199.193)
Suppose you are making a shared library using
R CMD SHLIB foo.cc
If there is a file called foo.c in the same directory, then it will be used
instead.
faheem ~/scratch/r-base>R CMD SHLIB foo.cc
gcc-3.0 -I/usr/lib/R/include -D__NO_MATH_INLINES -mieee-fp -fPIC -g -O2

R CMD SHLIB flags
How can one specify multiple extra flags to R CMD SHLIB? The example in
R-exts section 5.5
MAKEFLAGS="CFLAGS=-O3" R CMD SHLIB *.c
works for a single flag, but when I try
MAKEFLAGS="CFLAGS=-g -O2 -Wall" R CMD SHLIB *.c
only the first flag is used and the rest seem to be ignored (version
2.3.1, Mac OS X)

a couple of minor points about SHLIB
Dear People,
1) When I use the R search engine to find SHLIB (the text says "You can
search for keywords, function and data names and text in help page titles.
Usage: Enter a string in the text field below and hit RETURN"),
I get "no matches for "SHLIB" have been found!"
On the other hand, when I do

Makevars PKG_LIBS ignored by SHLIB (PR#9473)
Full_Name: Rick Sayre
Version: 2.4.0
OS: Windows
Submission from: (NULL) (138.72.27.164)
PKG_LIBS works fine on *nix
on windows, it seems to be ignored by the "SHLIB" script
so, R CMD SHLIB blah
properly uses PKG_CPPFLAGS and PKG_CFLAGS from Makevars, but PKG_LIBS is
ignored

trouble using R Mathlib as standalone
Dear People,
I am trying to use R's Math library as standalone, as documented in

are as follows:

ii r-mathlib 1.4.0-1 `GNU S' - Standalone R math library

using fmod in C code to be loaded into R
Dear People,
I wrote the following bit of C code and (along with other bits) called it
mycode.c, and compiled the file into a shared library to load into R,
using R CMD SHLIB mycode.c. This was Ok, but when I tried to load this
into R using dyn.load("mycode.so") I got the error

linear models
Dear R users,
I have a couple of linear model related questions.
1) How do I produce a fixed effect linear model using lme? I saw somewhere
(this may be Splus documentation since I use Splus and R interchangeably)
that using lme(...,random= ~ -1 | groups,...) works, but it gives the same
as lme(...,random= ~ 1 | groups,...), ie. fits a random effect intercept
term.
The reason why I want to do

testing for integer
Dear People,
Consider the following fragment of R code
choose <- function(n,r)
{
if( is.integer(n) && is.integer(r) && n > 0 && r >= 0 )
{
.C("choose",as.double(n),as.double(r),comb = double(1))$comb
}
else stop("n must be a positive integer and r a non-negative integer.")
}
This is a practice function (n choose r), which I

thick plot lines
Dear People,
In a qqplot I am doing, I get lines/points that are very thick. I've tried
setting the lwd variable to 0.1, but it doesn't seem to have any effect.
Also, I have set the value of lty to dashed, but I still get dots. The
command looks like
qqplot(cdf.inv(seq(0,1,length=size),theta,pos,len),empmargdistvec(len,theta,pos,size),

eps file not positioned properly in latex document
Dear People,
I am trying to include a barplot (see code below), in a latex document.
However, the plot appears in totally the wrong position. I know this is
not an R question as such, but the eps file is produced by R and I thought
that perhaps other people had had similar problems and could give me
pointers. Am I doing anything obviously wrong?
Sincerely, Faheem Mitha.
