Hi all,
I have a question about hist()
1)
t1 <- hist(c(1,2,3,4,5))
t1
$breaks
[1] 1 2 3 4 5
$counts
[1] 2 1 1 1
why is there 2 counts for 1? And should the counts be '1 1 1 1 1' ?
It depends on the way the bins are defined.
Had you forced a particular set of breaks you would get a different
set of bin boundaries.
t1 <- hist(c(1,2,3,4,5), breaks=c(1,2,3,4,5,6)-.1)
Is there any other function to count frequency of discrete data?
?table
> table(c(1,2,3,4,5))
1 2 3 4 5
1 1 1 1 1
Thanks.
