I have developed an R package that works under Win32, but when I attempt to build it on Win64, I get ERROR: loading failed for 'x64' More precisely, I developed and tested the package under Win32 and it works. But when I move to a 64 bit Windows 7 (Home Premium) system, and attempt to build both 32 bit and 64 bit packages, the 32 bit package seems to build, but the 64 bit build

I am trying to call a precompiled C function that uses a struct as one of it's arguments. I could write a wrapper function in C, but I was hoping there is some way to pack fields into an array of type raw that could be passed directly to the function. Here is some more detail. The C struct is simple, but has mixed types: struct STRUCT1 { long type; long nx; double

There is a contradiction between what the help page says and what constrOptim actually does with the constraints. The issue is what happens on the boundary. The help page says The feasible region is defined by ?ui %*% theta - ci >= 0?, but the R code for constrOptim reads if (any(ui %*% theta - ci <= 0)) stop("initial value not feasible") The following example

Hello,   Could someone help me please and to tell how to get the probability from empirical distribution (not parametric) for each data value (R function). For example, for normal distribution there is such a function like:   “pnorm(q, mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE)”   I need the same function only for the empirical distribution (which does not correspond to any typical

Hello: The example "integrate(dnorm,0,20000)" says it "fails on many systems". I just got 0 from it, when I should have gotten either an error or something close to 0.5. I got this with R 2.12.0 under both Windows Vista_x64 and Linux (Fedora 13); see the results from Windows below. I thought you might want to know. Thanks for all your work in creating

Ben Bolker gives some reasons why Numerical Recipes may be problematic as a starting point for R codes. CUP did a masterful job of marketing, but the license is restrictive as the links he gives points out. In some tests, I've also noted that some of the algorithms are less than stellar e.g, convergence tests in one or two optimization routines. Should we have a wiki item to help people find

If we do add an argument to get(), then it should be named consistently with the ifnotfound argument of mget(). As mentioned, the possibility of a NULL value is problematic. One solution is a sentinel value that indicates an unbound value (like R_UnboundValue). But another idea (and one pretty similar to John's) is to follow the SYMSXP design at the C level, where there is a structure that

Hi, The `quietly` argument of `require` is documented as follows: quietly: a logical. If ?TRUE?, no message confirming package attaching is printed, and most often, no errors/warnings are printed if package attaching fails. However: > require(foo, quietly=TRUE) Warning message: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :

And to facilitate this, R CMD check could remind you if you forgot to do the formal import.

Dear All, I regularly want to "apply" some function to an array in a way that the arguments to the user function depend on the index on which the apply is working. A simple example is: A <- array( runif(160), dim=c(5,4,8) ) x <- matrix( runif(32), nrow=4, ncol=8 ) b <- runif(8) f1 <- function( A, x, b ) { sum( A %*% x ) + b } result <- rep(0.0,8) for (i in 1:8) {

Dear all, I am trying to use the rstable(n, alpha, beta, gamma = 1, delta = 0, pm = c(0, 1, 2))) function to generate positive stable random numbers. For positive stable distribution, beta==1 and alpha is in (0,1), which defines random variables with support (0, infinity). So, I used rstable(100, 0.5, 1) for an example. I found that this gives me some negative numbers. For example, >

Well, I'm getting a warning (not an error) when the package doesn't exist. I interpreted "most often" to mean that suppressing warnings/errors is why you'd most often use this argument, as most packages don't emit startup messages. And technically there isn't a problem with attaching the package, since we don't even try to attach packages that don't exist.

Hi I am new to writing C code and am trying to write an R extension in C. I have hit a wall with F77_CALL(dgemm) in that it produces wrong results. The code below is a simplified example that multiplies the matrices Ab and Bm to give Cm. The results below show clearly that Cm is wrong. Am= 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Bm= 1 1 1 1 1

In November, we had a "bug repository conversation" with Peter Hagerty and myself: https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16065 where the bug report title started with --->> "exists" is a bottleneck for dispatch and package loading, ... Peter proposed an extra simplified and henc faster version of exists(), and I commented > --- Comment #2

I'm a week-old R user, and have become stuck trying to create usable CSV outputs for post-processing. I am using the package Rioja, which provides small datasets of results. I am running several analyses in a loop and iteratively adding the results to a *list* ("combined"). Within each iteration I use the following: > combined[[i]] <- performance(fit) With two iterations I

Dear R-devel, I am converting some stand-alone programs (mixed C and F77) to R functions. I've run into two issues that I haven't been able to resolve. I've looked at the R-exts manual and Readme files, but haven't found answers. (1) Can I link to a (Win32) static library? Is there some option to RCMD SHLIB that allows this? I've tried RCMD SHLIB myprog.c -l

In the help for ?integrate: >When integrating over infinite intervals do so explicitly, rather than just using a large number as the endpoint. This increases the chance of a correct answer ? any function whose integral over an infinite interval is finite must be near zero for most of that interval. I understand that and there are examples such as: ## a slowly-convergent integral integrand
