[R] Ordering of names on X- and Y-axis

[Matthew Keller]

Hi Michael,

This type of thing is pretty simple to do in R (take a look at ?plot
and then ?par - very useful... necessary actually... for graphing).
One way to do it is to use the "axis" function:


my.labels <- c("a","b","c","d","e","f","g","h","i","j")
plot(1:10,rnorm(10),axes=F,ylab="whatev",xlab="whatev")
axis(1,at=1:10,labels=my.labels, font=1, cex.axis=.85, las=1)
