Prints some basic information about the coefficients (for coef.grpnet
objects), observed cross-validation error (for cv.grpnet
objects), or the computed regularization path (for grpnet
objects).
## S3 method for class 'coef.grpnet'
print(x, ...)
## S3 method for class 'cv.grpnet'
print(x, digits = max(3, getOption("digits") - 3), ...)
## S3 method for class 'grpnet'
print(x, ...)
x |
an object of class |
digits |
the number of digits to print (must be a positive integer) |
... |
additional arguments for |
For coef.grpnet
objects, prints the non-zero coefficients and uses "." for coefficients shrunk to zero.
For cv.grpnet
objects, prints the function call
, the cross-validation type.measure
, and a two-row table with information about the min
and 1se
solutions.
For grpnet
objects, prints a data frame with columns
* nGrp: number of non-zero groups for each lambda
* Df: effective degrees of freedom for each lambda
* %Dev: percentage of null deviance explained for each lambda
* Lambda: the values of lambda
No return value (produces a printout)
Some syntax and functionality were modeled after the print
functions in the glmnet package (Friedman, Hastie, & Tibshirani, 2010).
