supressing linefeed at end of file
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

get vector data from contour
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?

Segmentation fault with expression on linux
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

CRAN packages maintained by you
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

package simecol uploaded to CRAN
Dear useRs, a new and completely re-worked version of the "simecol" package SIMulatiion of ECOLogical (and other) dynamic systems is now available on CRAN. Compared to the S3 based 0.2-x versions an improved object model using S4 classes was employed. Please ask me for assistance in case of incompatibility. Comments are welcome, Thomas Petzoldt

Linux distribution with gcc 4.8 and AddressSanitizer ?
Dear R developers, I've got an information from Prof. Ripley regarding a bug found with AdressSanitizer in one of our packages. It is now fixed, thank you for this information. Now, I would like to run AddressSanitizer myself before submitting the patched package to CRAN. Is there a recommendation of a suitable Linux distribution with gcc 4.8, ideally an ISO image or (even better) a

numerical issue in contour.default?
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 <-

Amo le curve femminili, senza avere una particolare predilezione per questo o quel tipo di curva. Per intenderci, il seno mi piace sia che sia piccolo, sia che sia grande. La sensazione al tatto poi ? sempre diversa e foriera di una straordinaria variet? di emozioni. Di quelli piccoli ? bello disegnare il profilo con un dito (solitamente s'inturgidisce subito... mhhh) di quelli grandi mi piace

package test failed on Solaris x86 -- help needed for debugging
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

vignette index not linked into HTML help system for package
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).

Hi, My Samba AD-DC installation is using CPU all time on a process. I'm trying everything to fix it, but without success.

nlminb: names of parameter vector not passed to objective function
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
