Column standardization of a data frame, matrix, or vector

Column standardization of a data frame, matrix, or vector

standard(X, center = 0, vardef = "n")

`X`	data frame, matrix, or vector If X contains non-mumeric variable, they will be left as they are.
`center`	= 1 to perform column centering only.
`vardef`	= "n-1" to use unbiased variance

When X is a data frame or matrix, the colums of which will be standardized.
NaN will be returned for those variables with 0 variance.

The standardized input.

standard( data.frame(id=paste("id",1:5,sep=""), diag(5), a="a") )
