[R] Histogram

[Ben Bolker]

plot(table(factor(x,levels=c("c","b","a"))))

is at least approximately what you want (the only complicated bit is 
reversing the order of the bars from the default alphabetical order)

substituting barplot() for plot() also works

you may want to use ylab="something" in the plot or barplot command to get 
a more descriptive axis label
