print.grpnet: print a grpnet object

In adelie: Group Lasso and Elastic Net Solver for Generalized Linear Models

print a grpnet object

Description

Print a summary of the grpnet path at each step along the path.

Usage

## S3 method for class 'grpnet'
print(x, digits = max(3, getOption("digits") - 3), ...)

Arguments

x	fitted grpnet object
digits	significant digits in printout
...	additional print arguments

Details

The call that produced the object x is printed, followed by a three-column matrix with columns Df, ⁠%Dev⁠ and Lambda. The Df column is the number of nonzero coefficients (Df is a reasonable name only for lasso fits). ⁠%Dev⁠ is the percent deviance explained (relative to the null deviance).

Value

The matrix above is silently returned
