Dear R devel list, Good morning; I'm with the Sage (http://www.sagemath.org) project. (Some of you might have seen my talk on this at last summer's useR conference). We have some rudimentary support for using R graphics in various cases, which has proved useful to many of our users who want to go back and forth between R and other capabilities within Sage. Unfortu...

> Looking for a recommended package that handles prime number computations. I'm not sure whether this would be helpful to you, but Sage (http://www.sagemath.org) has excellent number theory support and several ways to interface with R (which is included in the distribution of Sage). I use it myself to access several R packages I need to do analysis on data I produce in Sage/Python, and then send the data back to Sage for further processing. Of course...

If not, would someone be willing to develop a permanent fix for it (which I believe I could fund, within reason.) Thank You -- Chander Ganesan Open Technology Group, Inc. 1...

Trying to get 2.11.1 built on a solaris 10 machine. This particular machine I do not have root access so I have just created an area under my home to use. I am currently having issues in the src/library area most specifically with getting the datasets area built. Here is the output form my most recent compile: building package 'datasets' all.R is unchanged

Hi R-Devel, The Sage project (http://www.sagemath.org) has been working extremely hard for several years to create a viable free open source alternative to Maple, Matlab, Mathematica, and Magma. Numerous users have requested statistical functionality. Though Sage includes scipy and numpy, which have some statistical functionality, we've decide...

...ngs can cause non-PIC code to be generated even with that option. One is by the use of "computed gotos" which is a gcc extension. I'm wondering if R uses any of these. I'd love to track down this problem, so R can build with gcc. R is used in the Sage maths project http://www.sagemath.org/ and R is the only component of Sage which will not build with gcc on 64-bit Solaris x86. Many components will not build with Sun Studio, but this R issue means we need to have two compilers, not just one. -- A: Because it messes up the order in which people normally read text. Q: Why is t...

What are some effective ways to leverage the strengths of R and Mathematica for the analysis of a single data set? More specifically, are there any functions that can assist with any of the following? 1. Calling an R function from Mathematica. 2. Calling a Mathematica function from R. 3. Using XML or another reliable data format to pass vectors, matrices, and/or lists from one environment to

Dear all, I just changed from linux to a solaris server and I'm having trouble building R from source. I can't use the binaries because I don't have a permission to write to /usr/local. I followed the online instructions regarding the configuration with readline and the GNU version of iconv: ./configure --prefix=/u/fox/binaries

I've tried to build R 2.6.1 and 2.7.0 on Solaris 10 update 4 (SPARC) and both configure ok, so you might ask why I suspect there is a problem. I tried to build the maths program Sage http://www.sagemath.org/ version 3.0.3alpha1. Sage fails when building R 2.6.1 - (Sage includes R in the package). The relavant bit of Sage, which is only using an unmodified R configure script is: checking iconv.h usability... yes checking iconv.h presence... yes checking for iconv.h... yes checking for iconv......

Hello, Can anyone recommend a good example of web implementation of R? Can't seem to find anything on my own. Thanks in advance! Sam [[alternative HTML version deleted]]

...ave been less successful: ?x86? builds have failed on tests using complex arithmetic35, whereas on ?amd64? the builds have failed to complete in several different ways, most recently with relocation errors for libRblas.so. ############ I get that when trying to build R within Sage: http://trac.sagemath.org/sage_trac/ticket/9040 ld.so.1: R: fatal: relocation error: R_AMD64_PC32: file /export/home/drkirkby/sage-4.4.2/spkg/build/r-2.10.1.p1/src/lib/libR.so: symbol _init: value 0x228000984acd does not fit There's some info about this problem at http://developers.sun.com/solaris/articles/abou...

There's some information about the issue here http://trac.sagemath.org/sage_trac/ticket/9201 Does anyone have any suggestions? In particular, do you consider the failure of one or more of those modules sufficiently serious that the build of R should stop, or do you consider some failures like this not so serious, and so it is right for the build to continue?

Hi all, After searching for a decent compiler backend for ages (google sometimes isn't helpful), I recently stumbled upon LLVM. Woot!! I work on bignum arithmetic (I'm a professional mathematician) and have recently decided to switch from developing GPL'd bignum code to BSD licensed code. (See http://www.mpir.org/ which I contributed to for a while - a fork of GMP). Please bear with
