plot.sprinter: Plot function of sprinter fit
In hugogogo/sprintr: Sparse Reluctant Interaction Modeling

Description Usage Arguments Details Examples

Produces a two-panel plot of the sprinter object showing coefficient paths for both main effects and interactions.

1 2	## S3 method for class 'sprinter' plot(fit, which = 1, label = TRUE, index = NULL)

`fit`	Fitted `sprinter` object.
`which`	The tuning parameter considered in Step 2.
`label`	If `TRUE` (default), annotate the plot with variable labels.
`index`	Lambda indices to plot

A two panel plot is produced, that summarizes the main effects (left) and interaction (right) coefficients, as a function of lambda. Adopted from the function summary.rgam from package relgam by Kenneth Tay and Robert Tibshirani.
