[R] side by side histogram after splitting data by year

Mon Apr 18 01:29:41 CEST 2011

Will one of these do it for you:

> str(x)
'data.frame':   550 obs. of  5 variables:
 $ year    : Factor w/ 2 levels "one","two": 1 1 1 1 1 1 1 1 1 1 ...
 $ size    : Factor w/ 2 levels "large","small": 2 2 2 2 2 2 2 2 2 2 ...
 $ distance: num  30.9 121.5 46.1 46.1 46.1 ...
 $ taken   : int  10 2 12 1 4 1 10 3 5 5 ...
 $ mass    : num  13.88 2.78 16.65 1.39 5.55 ...
