Hi, I wrote a small patch to make it possible to get colored output from R running in a Linux terminal emulator. It's a dirty patch. I hope that someone with better knowledge of R source code and C programming will improve it. To force the use of Rstd_WriteConsoleEx function (src/unix/sys-std.c) I edited the file src/unix/system.c and I copied four lines from an AQUA #ifdef preprocessor directive and pasted them outside the condition. Then I edited the Rstd_WriteConsoleEx function to change the colors of the output: errors and warnings are red, normal output is green and numbers are yellow. If anyone is interested in trying the patch, here how to do it: 1) Copy the file rcolor.patch to R-2.14.0/src/unix/ directory. 2) Go to the R-2.14.0/src/unix directory and do the following command: patch -p3 < rcolor.patch 3) Compile R. 4) Put in your ~/.Rprofile: options(color.output = TRUE) The patch is attached and a screenshot is available at http://www.lepem.ufc.br/jaa/R_color_output.png -- Jakson Aquino
