[R-SIG-Finance] na.omit.xts unsupported type error

[Jeff Ryan]

Yes, currently only logical, integer and reals are supported at the C level. Mostly due to time/demand constraints.  

Since changing it, you are the first to mention it - so my suspicion is that it is reasonable. That said, I will add what I can in the C and try an cover remaining cases in R logic around. 

I'll also add something in the docs. 

Thanks,
Jeff
