In spareg: Sparse Projected Averaged Regression
generate_sparse R Documentation
Sparse random projection matrix
Description
Sparse random projection matrix
Usage
generate_sparse(rp, m, included_vector, x = NULL, y = NULL)
Arguments
rp
object of class 'randomprojection'
m
goal dimension, which will be randomly sampled in the SPAR algorithm
included_vector
integer vector of column indices for the variables to be
included in the random projection. These indices are produced in the
screening step of the SPAR algorithm.
x
matrix of predictors
y
vector of response variable
Value
(possibly sparse) matrix with m rows and
length(included_vector) columns.
