draw.mgcv_smooth

Plot basis functions

Description

Plots basis functions using ggplot2

Usage

## S3 method for class 'mgcv_smooth'
draw(
  object,
  legend = FALSE,
  use_facets = TRUE,
  labeller = NULL,
  xlab,
  ylab,
  title = NULL,
  subtitle = NULL,
  caption = NULL,
  ...
)

Arguments

object

an object, the result of a call to basis().
legend

logical; should a legend by drawn to indicate basis functions?
use_facets

logical; for factor by smooths, use facets to show the basis functions for each level of the factor? If FALSE, a separate ggplot object will be created for each level and combined using patchwork::wrap_plots(). Currently ignored.
labeller

a labeller function with which to label facets. The default is to use ggplot2::label_both().
xlab

character or expression; the label for the x axis. If not supplied, a suitable label will be generated from object.
ylab

character or expression; the label for the y axis. If not supplied, a suitable label will be generated from object.
title

character or expression; the title for the plot. See ggplot2::labs().
subtitle

character or expression; the subtitle for the plot. See ggplot2::labs().
caption

character or expression; the plot caption. See ggplot2::labs().
...

arguments passed to other methods. Not used by this method.
