I would like to prepare the data for barplot. But I only have the data frame
now.
x1=rnorm(10,mean=2)
x2=rnorm(20,mean=-1)
x3=rnorm(15,mean=3)
data=data.frame(x1,x2,x3)
If there a way to put data within a specific range? The expected result is
as follows:
range x1 x2 x3
-10-0 2 5 1 (# points in
this range)
0-10 7 9 6
...
I know the table function but I do not know how to deal with the range
issue.
Thanks in advance.
