plot.TrainedSLOPE {SLOPE}

Plot results from cross-validation

Description

Plot results from cross-validation

Usage

## S3 method for class 'TrainedSLOPE'
plot(
  x,
  measure = c("auto", "mse", "mae", "deviance", "auc", "misclass"),
  plot_min = TRUE,
  ci_alpha = 0.2,
  ci_border = FALSE,
  ci_col = "salmon",
  ...
)

Arguments

x

an object of class 'TrainedSLOPE', typically from a call to trainSLOPE()

measure

any of the measures used in the call to trainSLOPE(). If measure = "auto" then deviance will be used for binomial and multinomial models, whilst mean-squared error will be used for Gaussian and Poisson models.

plot_min

whether to mark the location of the penalty corresponding to the best prediction score

ci_alpha

alpha (opacity) for fill in confidence limits

ci_border

color (or flag to turn off and on) the border of the confidence limits

ci_col

color for border of confidence limits

...

words

Value

An object of class "ggplot", which will be plotted on the current device unless stored in a variable.
