[R] Histogram of multiple series on one histogram

[Jim Brennan]

Something like this!?!?
R>new
       a  
 [1,] 10 1
 [2,] 20 1
 [3,] 10 1
 [4,] 20 1
 [5,] 30 1
 [6,] 10 2
 [7,] 20 2
 [8,] 20 2
 [9,] 30 2
[10,] 30 2
[11,] 20 3
[12,] 20 3
[13,] 10 3
R>barplot(table(new[,2],new[,1]),beside=T,legend.text=c("a","b","c"))

Subject: [R] Histogram of multiple series on one histogram

Hello,
I have three sample, for example
	a<-c(10,20,10,20,30)
	b<-c(10,20,20,30,30)
	c<-c(20,20,10)

I would like to have only one histogram with these series,
I try the following code:
	hist(a)
	hist(b,add=TRUE,col="red")
	hist(c,add=TRUE,col="green")
but it's not that I want 

I would like an histogram with, from left to right, count of "10" for "a", 
count of "10" for "b", count of "10" for "c", count of "20" for "a", count
of 
"20" for "b", ... not overlapped

Thanks
