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 extend to more than 3 pairs)
Instead manually plotting as below, could you please point me out with easier
ways?
par(mfrow=c(3,1))
plot(dat$A_CH1+dat$A_CH2, dat$A_CH1-dat$A_CH2)
plot(dat$B_CH1+dat$B_CH2, dat$B_CH1-dat$B_CH2)
plot(dat[,5]+dat[,6], dat[,5]-dat[,6])
Thanks a lot for your help
