plot.glmnet {glmnet} | R Documentation |
Produces a coefficient profile plot of the coefficient paths for a
fitted "glmnet"
object.
## S3 method for class 'glmnet': plot(x, xvar = c("norm", "lambda", "dev"), label = FALSE, ...)
x |
fitted "glmnet" model |
xvar |
What is on the X-axis. "norm" plots against the
L1-norm of the coefficients, "lambda" against the log-lambda
sequence, and "dev" against the percent deviance explained. |
label |
If TRUE , label the curves with variable sequence numbers. |
... |
Other graphical parameters to plot |
A coefficient profile plot is produced. If x
is a multinomial
model, a coefficient plot is produced for each class.
