I recently downloaded the R schoolmath package and found a bug in the
"primes" function.

I'm not sure if it has been reported or not. I tried to report it to the
maintainer, but the email

address listed was no longer available.

Anyway ...

If you run the example from the document *primes(12,150)* one of the
numbers returned is *133*.

This is not a prime number since 7 x 19 = 1*33*.
The is.prim() function works fine and if you use it to verify the primes()
function you

will find several entries that return false.

> is.prim(primes(start=2, end=500))
