Hi Phil and Thomas, Thanks for your helpful feedback. I must admit my solution to creating the vector of colors lacked your elegance. In brief, I saved the output of colors() into a text file, saved all but 47 colours in that file and read it back as a data frame and used the first column of the dataframe as a vector of 47 colours. This roundabout method may have caused the problem because when I chose colours according to the commands sent by both of you things seemed to work just fine. Thank you very much for your feedback. Anjan
