Plot a gg_boost_error object

Source: R/plot.gg_boost_error.R
autoplot.gg_boost_error.Rd

The error path of a boosted multivariate tree fit against the boosting iteration, with the cross-validated optimal iteration marked.

Usage

# S3 method for class 'gg_boost_error'
autoplot(object, optimal = TRUE, ...)

# S3 method for class 'gg_boost_error'
plot(x, optimal = TRUE, ...)

Arguments

object

A gg_boost_error object.

optimal

Logical. Draw a vertical rule at the optimal iteration. Defaults to TRUE.

...

Passed to geom_line.

x

A gg_boost_error object.

Value

A ggplot object.

Details

The returned plot carries no theme, so it composes with any ggplot2 theme or scale. Several responses are drawn as facets rather than as coloured series, because the responses do not share a y scale.

Examples

# \donttest{
sim <- boostmtree::simLong(n = 25, n.time = 4, model = 1)$data.list
fit <- boostmtree::boostmtree(
  x = sim$features, tm = sim$time, id = sim$id, y = sim$y,
  M = 50, cv.flag = TRUE, verbose = FALSE
)
plot(gg_boost_error(fit))
