##### plot coefficients from a "glmnet" object

Produces a coefficient profile plot of the coefficient paths for a fitted "glmnet" object.

Keywords
models, regression
##### Usage
"plot"(x, xvar = c("norm", "lambda", "dev"), label = FALSE, ...)
"plot"(x, xvar = c("norm", "lambda", "dev"), label = FALSE,type.coef=c("coef","2norm"), ...)
"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.
