similar to: Linux distribution with gcc 4.8 and AddressSanitizer ?

Hello, I want to do simulations with an external simulation model. For this purpose I wrote a R-script which makes the pre- and post-processing of the data (generate scenarios, analyze results). The R-script writes the input file for the simulation with e.g. write(x, file="test.dat", ncolumns=10) The problem is, however, that this command (and even constructions with cat) will add a

I have a problem, that the plot of mathematical formula sometimes crashes R on Linux (SuSE 6.2 and 7.0 on a Dual PIII/500 machine with 1GB RAM). The problem occurs for example in demo("graphics"), i.e. in the last part were the mathematical symbols are plotted. There are several circumstances to reproduce this segmentation fault, but the following is one of the most simple examples. The

Dear R developers, I found a small issue while plotting contours of data containing both "usual" and "very small" numbers. It appeared with both R 3.0.1 and R-Devel on Windows, and I could reproduce it on Linux. Would it be possible to solve this before the upcoming release? Thanks a lot for developing this great software! Thomas Example: ######## set.seed(357) z1 <-

I have carried out a spatial interpolation (Kriging) using surf.gls() The contour plot looks very plausible and the image plot is o.k too. The problem is, hovever, that I need the vectorized isoplethes, as in contour(). Unfortunately, I found no solution to get the internal data from contour(). Is there a possibility to extract contour lines as x-y-polygon from a grid without hacking plot3d.c?

Hi all, we found, that R is not only *the* superior data analysis, graphics and statistics package, but it is also a general tool for implementing, running and teaching ecological models. Last week we held our second course "Modelling in Limnology" using R. Some material (code and docs) was produced for this purpose and may be interesting to someone else, so I put the tutorial

Hi, I have the same problem and, at a first look, the issues reported by the CRAN checks seemed easy to fix. However, after checking it again locally and on http://win-builder.r-project.org it appeared that GCC 4.9.3 (Windows, Rtools 3.4), same also on win-builder reports even more issues, especially legacy Fortran (mainly Roger's #2 and #3), but also "warning: ISO C forbids

Dear R developers, I recently observed a NOTE on several MaxOS X package checks: sh: line 1: gs: command not found !!! Error: Closing Ghostscript (exit status: 127)! /usr/bin/texi2dvi: thumbpdf exited with bad status, quitting. See for details: http://www.r-project.org/nosvn/R.check/r-release-macosx-ix86/simecol-00check.html or

Hello, I wonder why the control parameter REPORT is not supported by method SANN. Looking into optim.c I found an internal constant: #define STEPS 100 ... and decreasing this to 10 helped me fine-tuning the annealing parameters in an actual problem. Is there any reason why not passing nREPORT to samin and setting something like: STEPS = nREPORT / tmax Thomas P. -- Thomas Petzoldt

Dear R developers, I tried to use nlminb instead of optim for a current problem (fitting parameters of a differential equation model). The PORT algorithm converged much better than any of optim's methods and the identified parameters are plausible. However, it took me a while before spotting the reason of a technical problem that nlminb, in contrast to optim, does not pass names of the

Dear R developers, some of our packages come with additional programming examples in a directory called "/examples" which is created from "/inst/examples". This directory is linked from the docs (e.g. in inst/doc/index.html): <dl> <dt><a href="../examples/">examples</a>: <dd>Source code of examples </dl> Given, that we have a

Dear R developers, we have currently a 'mysterious' test problem with one package that successfully passed the tests on all platforms, with the only exception of Solaris x86 where obviously one of our help examples breaks the CRAN test. As we don't own such a machine I want to ask about a possibility to run a few tests on such a system: r-patched-solaris-x86 An even more recent

Hi Daniel, Chris suggested to talk to you about committing the AddressSanitizer (asan) run-time into the llvm tree (llvm-project/compiler-rt). Questions: - What is the preferred name for the directory? (asan? libasan? address_sanitizer? AdressSanitizer?) - Should the asan run-time use cmake, or just make, or what? The build is a bit tricky, especially for tests. We currently use make. - How

Dear R developers, I observed that the html help page index entry "Read overview or browse directory" for package vignettes is missing in recent R-devel. This happened on two independent computers (WinXP Prof. SP3, German) with R-devel compiled from sources svn rev. 48125 resp. 48128 It's the same for my own and also for more prominent packages as well (e.g. grid). The

Hello, first of all, thanks to LT for \pkg{codeutils}. I agree that it is indeed very useful to identify errors and also to encourage re-thinking past solutions. My problem: I want to compare different sets of related sub-functions which should be used alternatively by the same top-level function. Sets of related functions should be bound together (as lists) and the workspace should be as clean

Quick answers, I'm on txgiving break this week and not doing any real work, but I will be doing more compiler-rt work when I get back (initially focused at getting profile libs to come from compiler-rt on Linux et al).

Dear R developers, if one uses package.skeleton() to create a new package, then a file anRpackage.Rd with the following entries is prepared: \name{anRpackage-package} \alias{anRpackage-package} \alias{anRpackage} \docType{package} Packages created this way have a definite entry or overview page, so: ?anRpackage gives new users of a certain package a pointer where to start reading. This is

Hello, when testing packages under R version 2.6.0 Under development (unstable), in order to discover future compatibility issues, I recently get numerous "possible problem notes" for different (own and other contributed) packages containing Tcl/Tk code, e.g.: * checking R code for possible problems ...
