[R] R2.11.0 - rasterImage() and barplot fill-patterns
Hello Peter, Thank you, and the R core team, for the new release. I see that in R 2.11.0 there is now support for rendering of raster (bitmap) images through rasterImage(). I am wondering - can this be used to create a texture/fill-pattern for hist()/barplot() ? (A request made several times throughout the years on the mailing list. For example: http://osdir.com/ml/lang.r.general/2005-07/msg00799.html ) (I am also sending this e-mail to the maintainers of lattice, ggplot2 and gplots in the hope for more perspectives) With much respect, Tal Contact Details:--- Contact me: tal.gal...@gmail.com | 972-52-7275845 Read me: www.talgalili.com (Hebrew) | www.biostatistics.co.il (Hebrew) | www.r-statistics.com (English) -- On Thu, Apr 22, 2010 at 12:01 PM, Peter Dalgaard pd@cbs.dk wrote: I've rolled up R-2.11.0.tar.gz a short while ago.

Re: [R] R2.11.0 - rasterImage() and barplot fill-patterns
Hi, This idea was also discussed when Paul Murrell first announced the grid.raster function to R-devel, http://tolstoy.newcastle.edu.au/R/e8/devel/09/12/0912.html My personal conclusion was that vector fill patterns are generally better in terms of resolution and speed. Of course the situation might be different if one wanted to use a fancy image pattern, or if there was a fast implementation of tiling patterns at the C level. I wrote a proof-of-concept here --- my main issue is that the resulting grob is not vectorized, http://gridextra.googlecode.com/svn/trunk/inst/comparisonPattern.r Best, baptiste On 22 April 2010 14:10, Tal Galili tal.gal...@gmail.com wrote: Hello Peter, Thank you, and the R core team, for the new release.
