Error in uniroot(p, interval) : f.lower = f(lower) is NA

[BonnieMcLean]

Hey,

Thank you for this useful package! I have been using the cutoff() function together with the em function. However, sometimes the cutoff() function throws the following error: Error in uniroot(p, interval) : f.lower = f(lower) is NA

Below is the bimodal distribution for which I get the error (after putting the numbers into em(), and then into cutoff())

Do you have any idea what could be causing the error?

Thanks for the help!
