Description
A function to center (subtract mean) and/or scale (divide by
standard deviation) data column-wise in a computationally
efficient way.
Usage
scaler(x, center = TRUE, scale = TRUE)
Arguments
center, scale
Logical; determine if the data should be centered and/or scaled.
Value
The centered/scaled data, with attributes as in R's scale()
.
Details
Unlike its R counterpart scale()
, the arguments
center
and scale
can only be logical values
(and not vectors).
