autoplot.LearnerClassifCVGlmnet: Plot for LearnerClassifGlmnet / LearnerRegrGlmnet / LearnerClassifCVGlmnet / LearnerRegrCVGlmnet

Description

Visualizations for mlr3learners::mlr_learners_classif.glmnet, mlr3learners::mlr_learners_regr.glmnet, mlr3learners::mlr_learners_classif.cv_glmnet and mlr3learners::mlr_learners_regr.cv_glmnet using the package ggfortify.

Note that learner-specific plots are experimental and subject to change.

Usage

# S3 method for LearnerClassifCVGlmnet
autoplot(object, ...)
# S3 method for LearnerClassifGlmnet
autoplot(object, ...)
# S3 method for LearnerRegrCVGlmnet
autoplot(object, ...)
# S3 method for LearnerRegrGlmnet
autoplot(object, ...)

Value

ggplot2::ggplot() object.

Arguments

object

(mlr3learners::LearnerClassifGlmnet | mlr3learners::LearnerRegrGlmnet | mlr3learners::LearnerRegrCVGlmnet | mlr3learners::LearnerRegrCVGlmnet).

...

(any): Additional arguments, passed down to ggparty::autoplot.party().

Theme

The theme_mlr3() and viridis color maps are applied by default to all autoplot() methods. To change this behavior set options(mlr3.theme = FALSE).
