plot coefficients from a "glmnet" object
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, ...)
## S3 method for class 'mrelnet'
plot(
x,
xvar = c("norm", "lambda", "dev"),
label = FALSE,
type.coef = c("coef", "2norm"),
...
)
## S3 method for class 'multnet'
plot(
x,
xvar = c("norm", "lambda", "dev"),
label = FALSE,
type.coef = c("coef", "2norm"),
...
)
## S3 method for class 'relaxed'
plot(x, xvar = c("lambda", "dev"), label = FALSE, gamma = 1, ...)x |

A coefficient profile plot is produced. If x is a multinomial model,
a coefficient plot is produced for each class.
