[R] coloring a graph left or right of an abline

[Greg Snow]

Here is one approach:

> library(TeachingDemos)
> 
> x <- rnorm(1000)
> 
> hist(x)
> clipplot( hist(x, col='blue', add=TRUE), xlim=c(0.2,par('usr')[2] ) )
> clipplot( hist(x, col='red', add=TRUE), xlim=c( par('usr')[1], 0.2 ) )
> abline(v=0.2, col='green', lwd=5)
> 

Hope this helps,
