There seems to be a bug in image in R 13.1 (on windows 32 64 bits) and
on R-devel that is not present in R 13.0 and before.
The below creates a plot with many white lines, horizontal and vertical,
more or less regularly spaced. The effect is particularly dramatic when the
plotting window is made
Hello,
I am in the process of writing an R extension for parallelized MCMC, with
heavy use of compiled code (C++). I have been getting my feet wet by
implementing a simple matrix-vector multiplication function in C++ (which
calls a BLAS level 2 function dgemv), and comparing it to the '%*%'

Hi,
in save.image, it would be nice if there was a compression_level
argument that is passed along to save.
Or is there a reason for disabling the compression_level option for
saving workspaces, but enabling it for manually saving
The .Call overhead isn't the issue. If you'd like some insight into what you
are doing wrong (and right), you need to provide code for the list to reproduce
your timings with.
This is outlined in the posting guide as well.

Jeff,
In creating reproducible results, I 'partially' answered my question. I have
attached two scripts, 'mvMultiply.r' and 'mvMultiply.cc'. Please copy both
files into your chosen directory, then run 'Rscript mvMultiply.r' in that
directory while changing the two
Hi all, I was trying to create some vignette files for my newly
developed package, however wondering whether there could be any
simpler way to do so. In writing R extension it is advised to go
through Sweave route, however I have already got a big pdf file and
want to use this as package vignette.

It depends what you mean by 'vignette': the R docs have been unclear
(but R = 2.13.0 are more consistent). In most cases a 'vignette' is
an Sweave document, the vignette source being the .Rnw file, and the
vignette PDF the processed

Another workaround is to create a dummy vignette which does nothing
but include the pdf file. Something like this:
vignette.Rnw:
% \VignetteIndexEntry{vignette}
% \VignetteKeywords{keywords here}
% \VignettePackage{package name}
Also useful if you want to do an FAQ
