Description
Produces a coefficient profile plot of the coefficient or loss function
paths
Usage
## S3 method for class 'bsrr'
plot(
x,
type = c("tune", "coefficients"),
lambda = NULL,
sign.lambda = 0,
breaks = T,
K = NULL,
...
)
Arguments
x 
A "bsrr" object.

type 
One of "tune" , "coefficients" , "both" .
For "bsrr" with L_2 shrinkage:
If (type = "tune" ), the path of corresponding information criterion
or crossvalidation loss is provided;
If type = "coefficients" , a lambda should be provided and and this funciton provides a coefficient profile plot of the coefficient;
For "bsrr" object without L_2 shrinkage:
If type = "tune" , a path of lcorresponding information criterion or crossvalidation loss is provided.
If type = "coefficients" , it provides a coefficient profile plot of the coefficient.

lambda 
For "bsrr" with L_2 shrinkage: To plot the change of coefficients with lambda equals this value for type = "coefficients" or type = "both" .

sign.lambda 
For "bsrr" with L_2 shrinkage: A logical value indicating whether to show lambda on log scale. Default is 0.

breaks 
For "bsrr" object without L_2 shrinkage: If TRUE , a vertical line is drawn at a specified break point in
the coefficient paths.

K 
For "bsrr" object without L_2 shrinkage: Which break point should the vertical line be drawn at. Default is the optimal model size.

Other graphical parameters to plot

Value
No return value, called for plots generation
