Ok strangely both acf and pacf work with the xts object as long as the xts package hasn't been loaded. As soon as I load the package, I get the error

I'm trying to apply a acf/pacf function to a xts object and get the
following error:

Error in if (frequency > 1 && abs(frequency - round(frequency)) < ts.eps)
frequency <- round(frequency) :
 missing value where TRUE/FALSE needed

Are you by any chance using if() to perform some sort of variable transformation when you should really b using ifelse()? I have no idea why that might be influenced by loading the xts package. Show your full code and not just the error message if you want a more considered answer.
