print a glmnet object
Description
Print a summary of the glmnet path at each step along the path.
Usage
## S3 method for class 'glmnet'
print(x, digits = max(3, getOption("digits") - 3), ...)
Arguments
x |
fitted glmnet 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). In the case of a 'relaxed' fit,
an additional column is inserted, %Dev R which gives the percent
deviance explained by the relaxed model. For a "bigGlm" model, a simpler
summary is printed.
Value
The matrix above is silently returned

y = rnorm(100)
fit1 = glmnet(x, y)
print(fit1)
