Print and plot functions for the output from optPenalty.fused.grid which performs a grid based cross-validation (CV) search to find optimal penalty parameters.
Currently, only the complete penalty graph is supported.
# S3 method for optPenaltyFusedGrid
print(x, ...)# S3 method for optPenaltyFusedGrid
plot(x, add.text = TRUE, add.contour = TRUE, col = rainbow(100, end = 0.8), ...)
A optPenaltyFusedGrid-object print or plot.
Usually the output of
optPenalty.fused.grid.
A logical value controlling if the text should be added to the plot.
A logical value controlling if the contour lines should be added to the plot.
A character vector of colours used in the image plot.
Arguments passed on.
In print.optPenaltyFusedGrid the arguments are passed to print.matrix.
In plot.optPenaltyFusedGrid are passed to the standard plot function.
Invisibly returns the object (x).
