Produces a coefficient profile plot of the coefficient paths for a
fitted "glmnet" object.
Usage
## S3 method for class 'glmnet'
plot(x, xvar = c("norm", "lambda", "dev"), label = FALSE, ...)
## S3 method for class 'multnet'
plot(x, xvar = c("norm", "lambda", "dev"), label = FALSE,type.coef=c("coef","2norm"), ...)
## S3 method for class 'mrelnet'
plot(x, xvar = c("norm", "lambda", "dev"), label = FALSE,type.coef=c("coef","2norm"), ...)
Arguments
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.
type.coef
If type.coef="2norm" then a single curve per variable,
else if type.coef="coef", a coefficient plot per response
...
Other graphical parameters to plot
Details
A coefficient profile plot is produced. If x is a multinomial
model, a coefficient plot is produced for each class.
