similar to: Rcpp 0.7.0: R/C++ integration now even easier

Hello, I tried this posted on the R devel subforum but no help so far. Maybe the wider net will be fruitful. Probably a pretty simple issue. The short story goes, I'm writing C source code and compiling it in as *.dll in the windows terminal by R CMD SHLIB foo.c. It works, I'm on a 64-bit system. I have the lastest R 2.15.0 and Rtools, and I am using the gcc 4.6.3 compiler. However,

Hello, Novice programmer. I'm writing C source code and compiling it in as *.dll in the terminal by R CMD SHLIB foo.c. It works, I'm on a 64 bits windows system. I have the lastest R 2.15.0 and Rtools using the gcc 4.6.3 compiler. However, that was a hello world run, and I installed GSL for the 64 bit system for fast MCMC. The Rcpp package was easy to use, but I opted for a C with GSL

Hi, Below I have a mickey-mouse example using Oleg Sklyar's wonderful inline package. The question I have is, how do I return multiple values, say in a list? Inside the C code, I've also calculated 'sum'. How do I return this along with 'res'? Ultimately, I want to return multiple matrix results. Thanks in advance for any code snipplets/advice! Regards, Ken #

Hello, I?m with a problem in using nonlinear quantile regression, the function nlrq. I want to do a quantile regression o nonlinear function in the form a*log(x)-b, the coefficients ?a? and ?b? is my objective. I try to use the command: funx <- function(x,a,b){ res <- a*log(x)-b res } Dat.nlrq <- nlrq(y ~ funx(x, a, b), data=Dat, tau=0.25, trace=TRUE) But a can?t solve de problem,

by() fails for 1-column matrices and dataframes: X <- data.frame(a=1:10) g <- gl(2,5) by(X, g, colMeans) Suggested fix: --- by-old.R 2007-12-10 15:26:22.501086600 +0100 +++ by.R 2007-12-10 15:25:58.390477200 +0100 @@ -26,7 +26,7 @@ IND[[1]] <- INDICES names(IND) <- deparse(substitute(INDICES))[1] } else IND <- INDICES - FUNx <-

I have a fix to by.data.frame() that works for my example. Can anyone see a problem with this? The old code has: > get("by.data.frame",3) function (data, INDICES, FUN, ...) { ### code skipped to save space ans <- eval(substitute(tapply(1:nrow(data), IND, FUNx)), ### The problem seems to be here data) attr(ans, "call") <- match.call() class(ans)

This is a question and maybe an announcement. We've been discussing in the group that it would be nice to have a mechanism for something like "inline" C/C++ function calls in R. I do not want to reinvent the wheel, therefore, if something like that already exists, please give me a hint -- I could not find anything. If not, here is a working solution, please criticise so I could

Hi, I noticed that by() returns an object of class 'by', regardless of what its argument 'simplify' is. ?by says that it always returns a list if simplify=FALSE, yet by.data.frame shows: ---<--------------------cut here---------------start------------------->--- function (data, INDICES, FUN, ..., simplify = TRUE) { if (!is.list(INDICES)) { IND <-

summary: The function 'by' inconsistently strips class from the data to which it is applied. quick reason: tapply strips class when simplify is set to TRUE (the default) due to the class stripping behaviour of unlist. quick answer: This can be fixed by invoking tapply with simplify=FALSE, or changing tapply to use do.call(c instead of unlist executable example:

as.integer() truncates doubles toward zero, as Splus does (at least v. 6.1 under Windows does). Thus: > look <- (10 * seq(14)) - 76 > 10 * (73.1 + look) [1] 71 171 271 371 491 586 681 791 886 981 1101 1201 1301 1401 > as.integer(10 * (73.1 + look)) [1] 70 170 270 370 490 586 681 791 886 981 1101 1201 1301 1401 ... It is not documented in R! I propose appending

Has anybody tried to use Rmpi with the OpenMPI library instead of LAM/MPI? LAM appears to be somewhat hardcoded in the Rmpi setup. Before I start to experiment with changing this, has anybody else tried Rmpi with non-LAM MPI implementations?

I try to install Rmpi as root with install.packages("Rmpi"). It fails with: ... checking for x86_64-pc-linux-gnu-gcc -std=gnu99 option to accept ISO C89... none needed I am here /usr and it is OpenMPI Trying to find mpi.h ...

For those trying to move projects to 0.7.0, but still using 0.6.4, RubyGems supports this arcane syntax for the bin stubs that allow you to specify a gem version: spec _0.6.4_ /path/to/your/specs And for the ruby on rails plugin, you can make "rake spec" work by add the following two lines to the top of tasks/rspec.rake file: require ''rubygems'' require_gem
