[R] pairewise plots

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

[R] pairewise plots

Something like this should do it:

invisible(lapply(seq(1, length(dat), by=2), 
                 function(i) plot(dat[[i]]+dat[[i+1]], dat[[i]] -
dat[[i+1]])))

Your last line gives the hint:

for (i in 1:3) {
  c1 <- dat[,2*i - 1]
  c2 <- dat[,2*i]
  n1 <- colnames(dat)[2*i - 1]
  n2 <- colnames(dat)[2*i]
  plot(c1+c2, c1-c2, main=paste("Pair", i,":",n1, n2))
}

You can use for construction

for(i in c(1,3,5)) plot(dat[,i]+dat[,i+1], dat[,i]-dat[,i+1])

but if you want x or y labels formated differently, you probably 
need to ad some kind of expression in xlab (ylab) parameters.

Cheers

[R] pairewise plots

you could try something like this:

dat <- array(sample(24), dim=c(4,2,3))
par(mfrow=c(3,1))
apply(dat, 3, function(x) plot(rowSums(x), x[,2]-x[,1]))

I hope it helps.

Best,
Dimitris

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

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

Why would you want two columns with the same name?

If your data frame can be easily restructured (using reshape perhaps), 
one possible solution would be to use the lattice package:

require(lattice)
tmd(xyplot(c(A_CH1, B_CH1, C_CH1) ~ c(A_CH2, B_CH2, C_CH2) | gl(3, 4),
           dat, layout = c(3, 1)))

Note that 
1. This is with the data frame as it is, except that I assume the 
   last 2 columns are named C_CH1 and C_CH2
2. This plots the mean instead of the sum (but on the other hand, 
   it's a standard plot that way)
