Usage
"plot"(x, log.l=TRUE, type=c("cve", "rsq", "scale",
"snr", "pred", "all"), selected=TRUE, vertical.line=TRUE, col="red",
...)
Arguments
x
A cv.grpregOverlap
or cv.grpsurvOverlap
object.
log.l
Should horizontal axis be on the log scale? Default is
TRUE.
type
What to plot on the vertical axis. cve
plots the
cross-validation error (deviance); rsq
plots an estimate of
the fraction of the deviance explained by the model (R-squared);
snr
plots an estimate of the signal-to-noise ratio;
scale
plots, for family="gaussian"
, an estimate of the
scale parameter (standard deviation); pred
plots, for
family="binomial"
, the estimated prediction error; all
produces all of the above.
selected
If TRUE
(the default), places an axis on top of
the plot denoting the number of groups in the model (i.e., that
contain a nonzero regression coefficient) at that value of
lambda
.
vertical.line
If TRUE
(the default), draws a vertical
line at the value where cross-validaton error is minimized.
col
Controls the color of the dots (CV estimates).
