Hi,

I get this error message when I try to run cem (directly or via MatchIt) :

Error in FUN(c(1L, 0L)[[1L]], ...) : subscript out of bounds

I read and reread all the instructions, examples and demos but to no avail.

Is this a known bug ? Can it be an update problem (I'm running R 2.15.1) ?

Thanks,

François Maurice
