Hi Adrian,
Perhaps what you want is this:
ajdat<-structure(c(112L, 0L, 579L, 1L, 131L, 1L, 2234L, 2L, 2892L, 1L,
528L, 0L, 582L, 2L), .Dim = c(2L, 7L), .Dimnames = list(c("GN",
"CN"), c("DC5", "DC8", "DC14", "DC18", "DC19", "DC20", "DC23"
)))
library(plotrix)
twoord.plot(0.8:6.8,ajdat[2,],1.2:7.2,ajdat[1,],
main="Gene expression by chromosome loss/gain",
lylim=c(-2.2,10),lytickpos=-2:2,
xtickpos=1:7,xticklab=colnames(ajdat),
ylab="Chromosome loss/gain",rylab="GN",
type="bar",lcol=2,rcol=3,halfwidth=0.2)
