Plot the cross entropy loss from a cv.ppLasso or cv.gr_ppLasso object

Return the plot of the cross entropy loss from a cv.ppLasso or cv.gr_ppLasso object

Usage

# S3 method for class 'cv.ppLasso'
plot(
  fit,
  log.x = T,
  vertical.line = T,
  col.vertical.line = "blue",
  col.dot = "red"
)

# S3 method for class 'cv.gr_ppLasso'
plot(
  fit,
  log.x = T,
  vertical.line = T,
  col.vertical.line = "blue",
  col.dot = "red"
)

Arguments

fit

a cv.gr_ppLasso object.

log.x

whether the horizontal axis be on the log scale.

vertical.line

whether draws a vertical line at the value where cross-validaton error is minimized.
