All - I'm creating some plots in R that I would like to overlay on images that are created outside of R. I've used "image" before to plot image-like data within R, and have added vector plots on top of them, but I can't find a way to read in an external bitmap file into R and use that. Currently the external files are .png's, but I could generate a few other types, if something else might be easier to import. Thanks, -Mike

Following the posting guide suggests RSiteSearch("bitmap") which leads to http://finzi.psych.upenn.edu/R/Rhelp02a/archive/28384.html and http://finzi.psych.upenn.edu/R/Rhelp02a/archive/65284.html On Thu, 28 Dec 2006, Michael Wolosin wrote:> All - > > I'm creating some plots in R that I would like to overlay on images that > are created outside of R. > > I've used "image" before to plot image-like data within R, and have added > vector plots on top of them, but I can't find a way to read in an external > bitmap file into R and use that. > > Currently the external files are .png's, but I could generate a few other > types, if something else might be easier to import. > > Thanks, > -Mike > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >Charles C.

http://bioconductor.org/packages/2.0/bioc/html/EBImage.html This will read/write about 95 image formats into R, all those supported by ImageMagick and provide many image processing filters. If Windows is your platform, this version will work on Windows as well (the version release in Bioconductor 1.9 will not). It is a development version and even though it shows 1.9.12 now, it is already 1.9.14 on the SVN with many bug fixes. Go grab it, if using Windows, let me know I will send you a binary if it does not appear on the bioconductor page -- it takes several days until a new build.
