barplots - text direction

See las under ?par. You can often pass par parameters to higher-level 
graphics functions, so barplot(h, las=2) (for example) works.

HTH,

Simon.

If the variable names are too long to allow room for each to be displayed 
on a barplot, how can the direction of the text be changed?

a <- cbind(2.4,2.4,2.5,2.6,2.6,2.6,2.6,2.6,2.9,2.9,2.9)
b <- cbind(2.3,2.5,2.4,2.2,3.2,2.4,2.9,2.6,2.9,3.0,2.8)
h <- rbind(a,b)
colnames(h) <- 
c("one","two","three","four","five","six","seven","eight","nine","ten","eleven")
rownames(h) <- c("Pre-stage","Post-stage")
barplot(h, beside = T, legend = colnames(g), horiz = T, xlim = c(0, 5))


Many Thanks

a <- cbind(2.4,2.4,2.5,2.6,2.6,2.6,2.6,2.6,2.9,2.9,2.9)
b <- cbind(2.3,2.5,2.4,2.2,3.2,2.4,2.9,2.6,2.9,3.0,2.8)
h <- rbind(a,b)
colnames(h) <- c("one","two","three","four","five","six","seven","eight","nine","ten","eleven")
rownames(h) <- c("Pre-stage","Post-stage")
barplot(h, beside = T, legend = colnames(g), horiz = T, xlim = c(0, 5))

barplot(h, beside = T, legend = colnames(h), horiz = T, xlim = c(0, 5),
         las=1)

will do it.

Note: colnames(h) not colnames(g)

And note that rownames(h) will give a more sensible legend.
