Hello, I am trying to use Yan and Rossini's Makefile for cross building Windows versions of R packages in Linux with R 1.9.0. When compiling R with the mingw tools I get an error about expm1 being undeclared when first found at src/main/arithmetic.c:1019 If I fiddle a bit with it later on I also get errors about log1p bein undeclared. Any idea what should I look for? I am using R 1.9.0 in

A user of 'eha' told me that it failed to load in R-2.2.0 on Windows, and ideed, I checked and it fails with the error message "The procedure entry point expm1 could not be located in the dynamic link libary R.dll". I'm using expm1 (from the C math library on Linux, I would guess) in a couple of C functions. This didn't happen with R-2.1.1 (and it doesn't happen with

Dear Sirs, I was hoping you can help me, I am quite desperate in finding a solution for my problem! I have looked everywhere on the net and tried hundreds of codes, but I am still not anywhere close to the solution. I am quite new to R, so please excuse if this seems simple: I am trying to use R to analyse some stocks, but I can't get the theoretical confidence interval (95%) for my

Hello, Has anybody successfully called the Rmath library from C using the MS Visual Studio compiler (I am using Visual Studio 6.0)? I have compiled the Rmath library using gcc, and the 'test.c' program (which makes a call to qnorm) works fine when compiled with gcc. However, I get a fatal memory error when I run it after compiling it with Visual C. Would this memory problem be related

Hi: I followed the README in src/nmath/standalone/ to make the use the command "make shared" to make the libRmath.so file.

Dear R People: I am trying to build R-2.5.0 from source on a Windows machinee. I downloaded the tools and such, and started things off. I received some odd errors messages, looked on the R Search and found a similar problem. The suggestion was to re-load "ld.exe". I downloaded and installed everything again. Same problem. I am including my output.

Nobody managed to fix this when it was timely, and now PPC (at least PPC for desktop use) is a legacy platform. 2) Also I suspect that 3dnow is useless for 99.999% of FLAC users. And not so useful for the rest 0.001%. 3) A lot of code in

G'day all, I am working on problems where I have to calculate the logarithm of a sum or difference from the logarithms of the individual terms; so the functions logspace_add and logspace_sub which are part of R's API come in handy. However, I noticed that logspace_sub can have problems if both arguments are (very) small or the difference between the arguments are vary small. The logic

The derivative table resides in the function D. In S+ that table is extensible because it is written in the S language. R is faster but less flexible, since that table is programmed in C. It would be useful if R provided a mechanism for extending the derivative table, or barring that, provided a broader table. Currently unsupported mathematical functions of one argument include expm1, log1p,

Hi, pbirthday(, coincident = 2) starts to issue warnings (see (*) below) for larger number of classes (R 4.0.0, R-devel ./src/library/stats/R/birthday.R:47). The default coincident = 2 is computed as 1 - prod((c:(c - n + 1))/rep(c, n)) where c = classes. Using exp(log(...)), one can derive the return value if(n > 0) 1 - exp(sum(log1p(-(0:(n-1))/c))) else 0. Simplifying this a bit further one

The issue is that without an extensible derivative table or the proposed extensions, it is not possible to automatically produce (without manual modification of the deriv3 output) a function that avoids catastrophic cancellation regardless of the working range. Manual modification is not onerous as a one-time exercise, but can be time consuming when it must be done numerous times, for example

Hey, So I tried to fix these errors, and have everything compiling now... not too difficult, just annoying. error C2248: 'llvm::EquivalenceClasses< > > ElemTy>::ECValue::ECValue' : cannot access private member declared in class > 'llvm::EquivalenceClasses<ElemTy>::ECValue' C:\Program Files > (x86)\Microsoft Visual Studio 10.0\VC\include\xmemory 208

There is a small typo in the Source section of the help page for log1p: Source: 'log1p' and 'expm1' may be taken from the operating system, but if not available there are based on the Fortran subroutine 'dlnrel' there -> they Jen > sessionInfo() R version 3.0.2 (2013-09-25) Platform: x86_64-unknown-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8

Full_Name: Morten Welinder Version: 2.1.0 OS: src only Submission from: (NULL) (216.223.241.212) Now that pcauchy has been fixed, it is becoming clear that qcauchy suffers from the same problems. qcauchy(pcauchy(1e100,0,1,FALSE,TRUE),0,1,FALSE,TRUE) should yield 1e100 back, but I get 1.633178e+16. The code below does much better. Notes: 1. p need not be finite. -Inf is ok in the log_p

Dear R users, I've been trying to build R from sources (in Windows) using Dr. Goto's BLAS, unsuccessfully! I've followed the instructions in Section 3.1.2-3.1.3 of "R Installation and Administration" manual (but maybe I did something wrong), but I keep receiving the following error: -- initially I get -- make: ./Rpwd.exe: Command not found make[1]: ./Rpwd.exe: Command not
