Any data object (especially useful for multiple columns of a data.frame).
Takes the data (by columns if necessary) and subtracts out the mean and then divides by the standard deviation. The result is a standard normal z score.

The result is a matrix. One may wish to convert to data.frame or use as.data.frame(Make.Z(x))
