I am trying to produce frequencies in defined intervals however I can't seem
to figure out how to get R to bin my data the way I want it to.

 

I have several thousand lengths of fish that I want to be binned as follows:


 

Ex.

 

Length      Bin

 

209         200

219         210

431         430

727         720

 

That is, bins with any length equal to or greater than the lower cutoff, but
smaller than the next higher cutoff should be included.  I have tried using
the right=FALSE and include.lowest in the hist function but it still puts
lengths that is greater than the cutoff into the next bin.

All software seems to bin right, but fish nerds do it a little different.

 

 

 

Thanks!
