R help - Apr 2012 - Histogram classwise

Hi 
I have a data class wise. I want to create a histogram class wise without
using for loop as it takes a long time 
my data looks like this

x	class
27	1
93	3
65	5
1	2
69	5
2	1
92	4
49	5
55	4
46	1
51	3
100	4




-----
Thanks in Advance
        Arun

I'm not entirely sure what you mean, but maybe split() and lapply() would
help?

You might want to look at the lattice or ggplot2 packages, both of
which can create a graph for each of the classes.
