split(x,f,drop=FALSE,...)
## S3 method for class 'rcomp'
split(x,f,drop=FALSE,...)
## S3 method for class 'aplus'
split(x,f,drop=FALSE,...)
## S3 method for class 'rplus'
split(x,f,drop=FALSE,...)
## S3 method for class 'rmult'
split(x,f,drop=FALSE,...)
## S3 method for class 'ccomp'
split(x,f,drop=FALSE,...)
          

Arguments

x

a dataset or a single vector of some type

f

a factor that defines the grouping or a list of factors
