Hello, As I am new to the use of R, could someone give a hint on how we can label (color will do) the digestion plots for a collection of arrays. Thanks much. Harry Hurd Dept of Statistics University of North Carolina [[alternative HTML version deleted]]

If you are not using AffyRNGdeg and are just plotting your own data, one example involving use of color is "plot(1:10,col=2); lines(2:11,col=3)". If you type col2rgb(2) or col2rgb(1:10), you will verify that the color you see is in fact the RGB triplet ( 255, 0, 0 ). You might want to check out the reference manual sections on items such as "col2rgb", and "lines". Assuming you are using AffyRNAdeg, you might see that it can take a named "cols" parameter to let you supply a vector of colors, such as 1:10. Cols is used in the AffyRNAdeg routine as follows: ... for (i in 1:dim(mns)[1]) lines(0:((dim(mns)[2]-1)), mns[i, ],col=cols[i]) So if you are using AffyRNAdeg, you can just pass an extra named parameter using "cols=". If you are new to R, just set that named parameter to 1:10, for example.
