Hi Louisa,
I'm still not entirely sure of what you're trying to do, but I'll attempt an
answer to your question nevertheless.
Let's assume that this frequency table was created from a dataset that
comprised only a single column of "Chest" values. If you want to recreate
this original column, you'd have to use
temp1 = rep(temp$Chest,temp$Count) ;
Then, you could redefine your break points and let the hist() function count
the number of data entries in each new category.
Hope this helps,
Luc

Hi,
Sorry, yes that would be a better idea, Luc!
Here are the first few lines of the frequency table..
Count Chest
1 3 33
2 18 34
3 81 35
4 185 36
5 420 37
In my previous email I said the sample size was 100, I just meant that as
an example, obviously it's far greater than that..

create a histogram table from it, but I obviously first have to expand the
data - to the sample size of 100. I want to use the command rep(), but I'm
not sure how to go about it..I tried using the code:
