Dear all, i have the attached data called "new" as data.frame. First I have only three columns called Var1, Var2 and Freq and with bind I attached the column test for a color specification (TEST DATA below). With this plot function (require packages lattice) dotplot(reorder(Var1, rep(score, cl.count)) ~ Freq | Var2, data = DATA, origin = 0, type = c("p", "h"), main = paste("The", top, "Top Ranking Features"), xlab = xlab, layout=c(cl.count,1), col=new["test"]) i want to plot the data. Score indicated the scores which was calculated in a previous step and in my case i extracted 40 score values (each for every row name). Attached below and shown as a matrix. cl.count indicates 3 groups (RA, OA and JT) Sadly, the colors are not in this way i like. If I look at the new[,"test"] column only the rows 1,3,7,and 12 have the value "blue" and all other rows have the value "green". But when I look at my created plot there are 12 lines with a blue color. Can anybody explain me, why it is not possible to get the blue color only in the rows where "blue" is indicated? Glad to hear from you. All the best Peter #### DATA##### Var1 Var2 Freq 208869_s_at JT 10.6802376685463 203394_s_at JT 10.0160470327077 201533_at JT 9.58401500697783 216520_s_at JT 9.07764840614892 210999_s_at JT
