Re: [R-pkg-devel] robust download function in R (similar to wget)?

libcurl (which the RCurl & curl packages are built on) do not inherently have retry or resume partial capabilities, but those could be packaged up into a "robustdownloader" package. There's no guarantee of wget or curl binaries being on a system (especially Windows, even with an Rtools installation

Re: [R-pkg-devel] Compiler choice on CRAN (R-windows-oldrel)

Thanks Uwe. Very clear. I'll post the solution I chose, so people can find it later. The problem is that GCC <= 4.6.3 (at least) does not implement OpenMP reduction statements. So now I do something like this: #ifdef _OPENMP #include #endif #ifdef __GNUC__ #if __GNUC__ <= 4 & __GNUC_MINOR__ <=

I am creating this package that has to download data from some sources that are a bit unstable/unreliable. The problem is described in this issue . Is there a more "robust" download fucntio

Re: [R-pkg-devel] Compiler choice on CRAN (R-windows-oldrel)

I don't have hard info on ABI compatibility between gcc versions, but there have been issues in the past, at least with with gfortran. Now, many people/schools will have R-3.2.x installed, built with gcc 4.6.y. We cannot retroactively recompile their installation, nor expect them to install a n

[R-pkg-devel] Compiler choice on CRAN (R-windows-oldrel)

Dear listers, Compilation of my gower pkg fails on R-oldrel-windows. I am pretty sure that this is because it uses gcc 4.6.3 which has limited support for OpenMP (the errors are the same as I got on the old travis-ci build environment, see my related question[1]). Now, according to the Rtools pa
