Dear R users, I have a data generated as the following, dat <- data.frame(matrix(sample(24), nrow=4)) dimnames(dat) <-list(rownames=c('g1','g2','g3','g4'), colnames=c("A_CH1","A_CH2","B_CH1","B_CH2","C_CH3","C_CH3")) » dat A_CH1 A_CH2 B_CH1 B_CH2 C_CH3 C_CH3 g1 16 24 7 9 14 20 g2 4 10 19 22 5 17 g3 11 18 21 12 13 1 g4 2 3 15 6 23 8 I am trying to plot them pairwise by column(might...

...help. The above solution also opens my mind that I could convert my data to an array. dat <- data.frame(matrix(sample(24), nrow=4)) dimnames(dat) <-list(rownames=c('g1','g2','g3','g4'), colnames=c("A_CH1","A_CH2","B_CH1","B_CH2","C_CH1","C_CH2")) Sorry for the typo. (C_CH1, C_CH2) dat2 <- array(unlist(dat), dim=c(4,2,3)) and then plot them using Dimitris' solution. Other statements of converting form are welcomed... Thanks again.
