Hello,
Thanks very much for your kind response. Yes, if I multiply by the
width "35", the area should be equal to one.
How can I plot the probability bars rather than density bars? That
is, I would like the height of the first bar to be 0.279, which is the
probability that the variable falls between 0 and 35.
If you want probabilities rather than densities you should be using
barplot() rather
than histogram:
TBL <- table(Y1)
barplot(TBL/sum(TBL))
cheers,
Rolf Turner
