Since these are color strings, you can use functions in the grDevices package (other others) to manipulate them. E.g., you can convert them to various color spaces and perhaps use the mean in one of those spaces as your 'average color'. > myColors <- c(One="#FF7C00",Two="#00BF40",Three="#FFFF00") > col2rgb(myColors) One Two Three red

Hi, I'm wondering if someone has solved the problem of converting very large integers to hex. I know about format.hexmode and as.hexmode, but these rely on integers. The numbers I'm working with are overflowing and losing precision. Here's an example: x <- "6595137340052185552" # stored as character as.integer(x) # warning about inaccurate conversion

Hi, How would you calculate the "mean colour" of several colours, for example c("#FF7C00","#00BF40","#FFFF00")? Yours, Atte Tenkanen

I'd like to use an R CMD BATCH script as part of a chron job that is set up to run every hour. The trouble is that the script creates a graphical output in a file via png(), and apparently this in turn works through X. When cron invokes the job, no X server is available -- I suppose that the DISPLAY variable is not set -- and so R exits with an error message in the output file. (If I run the

A coworker got tired of having to type 'yes' or 'no' after quitting R: he never wanted to save the R workspace when quitting. So he added assignInNamespace lines to his .Rprofile file to replace base::q with one that, by default, called the original with save="no".. utils::assignInNamespace(".qOrig", base::q, "base")
