scale {compositions} | R Documentation |
The dataset is standardized by optional scaling and centering.
## S3 method for class 'acomp': scale(x,center=TRUE, scale=TRUE) ## S3 method for class 'rcomp': scale(x,center=TRUE, scale=TRUE) ## S3 method for class 'aplus': scale(x,center=TRUE, scale=TRUE) ## S3 method for class 'rplus': scale(x,center=TRUE, scale=TRUE) ## S3 method for class 'rmult': scale(x,center=TRUE, scale=TRUE)

scaling is defined in various ways for the different data types. It is always performed as an operation in the enclosing vector space. Not in all cases an independent scaling of the different coordinates is appropriate. This is only done for rplus and rmult.
a vector or data matrix, as x and with the same class, but acordingly transformed.
