[R] npmc function: 'x' must be atomic

[Patrick Drechsler]

Hi,

I'm having trouble getting the function `npmc' working. I have a
2 column 30 row table called `mydata':

> npmc(mydata, df=2, alpha=0.05)
Error in sort(unique.default(x), na.last = TRUE) : 
	`x' must be atomic
> is.atomic(mydata)
[1] TRUE

Is there anything I have overlooked? Am I invoking the function
correctly? I wasn't able to find any hints in the archives
either.

TIA,

Patrick
