[R] [R-pkgs] Announcing Rpad, a web-based workbook-style interface for R
Rpad is an interactive, web-based analysis system. Rpad pages are interactive workbook-type sheets based on R. Rpad is an analysis package, a web-page designer, and a gui designer all wrapped in one. Rpad pages are run from the browser and connect to R running on the server (the same server that hosts the web pages). Rpad includes the R package RpadUtils, which adds convenient code to generate HTML widgets and convenience functions for generating web graphics (png). For more information and demonstrations, please see: http://www.Rpad.org/Rpad/ Key features include: (*) WYSIWYG editing -- The browser page is editable, so you can add comments or change the code or input data. (*) GUI's -- Create GUI elements with R or with the Rpad interface. (*) Fast -- No browser refreshes. The R process on the server stays alive while the browser page is open, so once the page is up and running, it is quite responsive. (*) HTML output -- Create fancy HTML output using Eric Lecoutre's R2HTML. (*) Simple plotting -- Has convenience functions to simplify creation and presentation of web-friendly graphics. (*) Flexible -- You can add features in a number of ways with javascript and/or R. (*) Cross platform -- Rpad pages work in Internet Explorer v5.5 or greater and Mozilla (Firefox or Suite). The server-side code works in Apache in Linux or Windows (although not as well in Windows). (*) Open source -- Rpad brings together several powerful open-source technologies, specifically: R, Mozile, HTMLArea, Statistics-R-0.02, JSCookMenu, Apache, and R2HTML. Feel free to use the r-sig-gui mailing list (https://stat.ethz.ch/mailman/listinfo/r-sig-gui) for any feedback on Rpad, the demonstration pages, and especially for feedback and questions on installing your own Rpad server. - Tom -- Tom Short EPRI PEAC, www.epri-peac.com T.

Re: [R] Confused about specifying plot colors as RGB values
Paul Roebuck wrote: Based on reading 'rgb' So, why are you not using rgb()? documentation, I would have thought the following would have produced identical results. Can someone explain how to make this happen? I need to be able to specify an array of rgb values for the 'col' parameter. colnames.col - c(black, red, blue, green) colnames.rgb - apply(as.matrix(colnames.col), 1, col2rgb) dimnames(colnames.rgb)[[2]] - colnames.col baseline - 1:32 offset2 - 2*baseline offset3 - 3*baseline offset4 - 4*baseline offsets - cbind(offset2, offset3, offset4) # Produces expected result X11() matplot(baseline, col = colnames.col[1], type = l) matlines(offsets, col = colnames.col[-1]) # Displays a ??yellow?? line X11() matplot(baseline, col = as.matrix(colnames.rgb[,1]), type = l) matlines(offsets, col = colnames.rgb[,-1]) Yes, because 255 is a color number that is interpreted as yellow. Why do you think you can specify a matrix of integer values and R knows that you mean an rgb representation rather than color numbers? What you can do now (but I don't think you really want to do it this way!) is: cn - apply(colnames.rgb, 2, function(x) rgb(x[1], x[2], x[3], maxColorValue=255)) matplot(baseline, col = cn[1]), type = l) matlines(offsets, col = cn[-1]) Uwe Ligges -- SIGSIG -- signature too long (core dumped) __ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html __ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Figure out how to make the crash reproducible, then see if you can figure out what causes the crash. Try it out on the 2.0.0 alpha release to see if the bug has been fixed. If it looks like it hasn't, use bug.report() to report all the details. If you can't make it reproducible, it probably won't be fixed. If you can, and it's an R bug, it probably will be: but it may well be an ESS or Emacs bug.
