# plot.glmnet

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

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

object.

- Keywords
- models, regression

##### Usage

```
# S3 method for glmnet
plot(x, xvar = c("norm", "lambda", "dev"), label = FALSE, ...)
# S3 method for multnet
plot(x, xvar = c("norm", "lambda", "dev"), label = FALSE,type.coef=c("coef","2norm"), ...)
# S3 method for 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.
