[r] Can I calculate z-score with R?

R, correlation: is there a func that converts a vector of nums to a vector of standard units

By reading stackoverflow's comments, I found z-score maybe calculated with Python or perl, but I did not comes across any for R yet. Did I miss it? Is it possible to be done with R?

As (http://en.wikipedia.org/wiki/Standard_score.)

z-score = (x-µ)/s

x is a raw score to be standardized; 
µ is the mean of the population; 
s is the standard deviation of the population. 

I believe there are R packages designed for this? Where can we found them? Or similar package for normalization?

if x is a vector with raw scores then scale(x) is a vector with standardized scores.

Or manually: (x-mean(x))/sd(x)
