[R] is zscore() deprecated or Windows only?

[John Christie]

Hi
	I was looking through the help on how to get standardized scores and 
came across an anomaly.  The help.search("zscore") reports there is 
such a function in R.base.  However, when I try to get help on zscore 
it reports no such function and says that R.base in built for win32.
	I'm running the Mac OS X version of R with the smorgasboard of 
packages that are included in that download.
