I am a true R novice aonly using it for this function ;) I am trying to use color2D.matplot to form a image of my data using the following conditions
color2D.matplot(fi1, c(dr), c(dg), c(db), nslices=7, ylab='Species', xlab="gene", show.legend=TRUE) where fi1 is my matrix. I have a matrix with 36 columns and 130 rows. most entries are 1 or 0 and I am trying to get this function to plot these as either 0 = white or 1 = black. This is fine but one column contains entries between 0 and 7. I would entries between 2 and 7 to be different colors (as this is what I am trying to show although I also need to see the black and white areas) using the following: > dr = c(1,0,1,0,0) > dg = c(1,0,0,1,0) > db = c(1,0,0,0,1) I can get some color to work but I cannot get them all as if I but in a c() range equalling 0-7 (i.e. one color for each number I get the following. I cannot figure out from the documentation why it will not let me do what I want :( Error in rescale(x[segindex], redrange[c(seg, seg + 1)]) : rescale: can't rescale a constant vector! help please someone... -- View this message in context: http://www.nabble.com/color2D.matplot-tf4760527.html#a13614400 Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
