If you look at the help for the tkBrush function in the TeachingDemos package, the examples show the definition of a function called colhist.  That function may do what you want.

Hope this helps,

Subject: [R] Help with histograms
 

I would like to make one histogram combining two value vectors. One vector has more than 50 entries and the other only has 16. Both vectors contain dates in the POSIXct format. I need to be able to highlight the 16 entries from the smaller data set. 

Is it possible to do this with the hist function? Which function should I use?

Sloan
