Hi, Is it possible that I could see some of your functions and/or results of those functions(Eric, Charles, Stephan). It's more about that I'd like to see what already has been accomplished and the way that was chosen thus circumventing reinvention and getting an overview.

I am interested in your R functions, if you will make them available. Unfortunately, making a package for CRAN is (in my opinion) WAY too hard on Windows, and I've given up, but I hope that you do not. I second Stephan Matthiesen's recent suggestion that you make your image processing functions available to fellow R users, if not on CRAN, then perhaps as ascii files from your website. Thanks.

I routinely do image analysis in R. Yes, it is relatively slow compared to dedicated solutions, but I like the smooth integration with the associated statistical analysis and the ability to have a single script that performs the image analysis and multiple files and subsequent statistical analysis, and with modern computing equipment R is fast enough for my purposes. I have a variety of standard image processing functions written in R, but have yet to distribute them because most people choose not to perform image analysis in R for the previously stated reasons. So in general I would agree that R is sub-optimal for image processing (and this is certainly outside the realm of things R was intended to do if I read the early mailing list archives correctly). However, it can be done and it might be desirable to do so from a work-flow perspective. -Eric > Greetings > > Thomas Kaliwe This email message, including any attachments, is for the\ s...{{dropped}} ______________________________________________ R-help@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
