getPath: Get the regularization path

In bozenne/lava.penalty: Penalized Latent Variable Models

Description

Extract the regularization path from a lvm object

Usage

getPath(x, ...)

## S3 method for class 'plvmfit'
getPath(x, coef, ...)

## S3 method for class 'regPath'
getPath(x, coef, V, lambda = "lambda1.abs",
  keep.indexChange = FALSE, keep.index = TRUE, keep.optimum = TRUE,
  path.constrain = FALSE, only.breakpoints = FALSE, increasing = TRUE,
  row = NULL, ...)

Arguments

x	a plvmfit object or a regPath object
...	additional arguments to be passed to low levels functions
coef	names of the coefficients to extract. Can also be "coef0" or "coefn0" to extract the number of 0 or non-0 coefficients
V	matrix containig the constrains
lambda	names of the penalization parameter to extract.
keep.index	should the index of the knot be kept in the output.
keep.optimum	should the column indicating the optimum and the fit be kept in the output.
path.constrain	should the column containing the active constrains be added to the output.
only.breakpoints	should the path be extracted only at the breakpoints
increasing	should the path be extracted by increasing value of regularization parameter
row	the index at which the path should be extracted
