Hello,
I need to make a histogram with variable x bin ranges. For example my bins
are 0-15, 15-25, 25-40 etc. Any suggestions?
Thanks!
Hi cbarcelo,
You can just do this:
x<-sample(0:40,100,TRUE)
hist(x,breaks=c(0,15,25,40))
which will produce densities, or:
hist(x,breaks=c(0,15,25,40),freq=TRUE)
which will display counts, but complain about it, or:
barplot(hist(x,breaks=c(0,15,25,40))$counts,
names.arg=c("(0-15]","(15-25]","(25-40]"))
which may be what you want.
Jim
