similar to: a couple of minor points about 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 make[1]: Entering directory `/home/faheem/research/cftp' gcc -I/usr/lib/R/include

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

Dear R People, in the R FAQ (in the R Programming section) it says ********************************************************************** How can I change compilation flags? =================================== Suppose you have C code file for dynloading into R, but you want to use `R CMD SHLIB' with compilation flags other than the default ones (which were determined when R was built).

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 "/home/faheem/research/thesis/sim/ms/ms.so":

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 > dyn.load("mycode.so") Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to

Hi, Consider the following file. ******************************* foo.cc ******************************* #include <R.h> #include <Rinternals.h> #include <iostream> ******************************* R CMD SHLIB foo.cc gives scads of errors. I've use C++ extensively with R before (using C linkage) but not with Rinternals.h. I'm puzzled. The errors make no sense to me. Am

Dear rsync people, I have just started using rsync for backups. I have had a couple of issues. Note I'm trying to use rsync as user using ssh between two machines both running Debian GNU/Linux potato (2.2r3). The local machine is currently running 2.4.6-1 and the remote 2.3.2-1.2. 1) When I run rsync with the vv option, stuff scrolls of my screen faster than I can read it. I was wondering if

Dear R people, I have the following simple bit of code to make a plot. I want to suppress tick marks on the axes of the plot. I've been trying everything I can think of to do so, but have been unsuccessful. Can you help me? If you reply, please cc me, I'm not currently subscribed to the list. Thanks in advance. Sincerely, Faheem Mitha. num <- 1:i inc

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. PS.

Dear People, I have been trying to perform concatenation operations on lists without success. Consider the following example. > x <- runif(2) > y <- runif(2) > z <- runif(2) > xy <- list(x,y) > xyz <- list(x,y,z) I want to have a function foo such that foo(xy,z) is the same as xyz. This appears not to be as easy as I thought, though there must be a way. For example

I have the following question, which is elementary but I am unable to answer. In a for(i=10) loop, I am trying to represent the 10 1-dimensional vectors l1, l2,... l10 by some expression that will run through these values. ie. soppose I want to add l1 + ... + l10 I could go x <- 0 for(i in 1:10){ x <- x+ l(i)} This should return x to be the sum of the 10 li's for i from 1 to 10

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

Dear R People, I getting some curious behaviour with the integrate function. Consider the function foo <- function(x) { if(x==0) 4 else 0 } I get the error > integrate(foo,0,1) Error in integrate(foo, 0, 1) : evaluation of function gave a result of wrong length But now consider foo <- function(x) { ifelse(x==0,4,0) } > integrate(foo,0,1) 0 with absolute error

Dear people, I compiled a bit of C code into a shared library cftpR.so, and load it into R at runtime using > dyn.load("cftpR.so") This works fine, however when I put .First <- function() { dyn.load("/home/faheem/research/cftp/cftpR.so") } (using absolute path names; also tried with just dyn.load("cftpR.so")), into my .Rprofile to load the library at

Dear R people, I need to do some work with clustering, but know next to nothing about it at present. R has (at least) three clustering packages, cluster, mclust, cclust. I was wondering if someone can direct me to some good books where I could find documentation and background on the functions in these packages. The html help in these packages lists the following as references. Can people

Dear R People, I want to include a barplot corresponding to a simple discrete probability distribution in a LaTeX document. I decided to use the pictex driver. After a certain amount of messing about, I came up the stuff below. It does not look too bad, however, there is one very obvious piece of weirdness, ie. the y axis terminates at 0.1 and does not extend down further. I tried to adjust this
