thematic_save_plot: Capture a thematic plot as a saved file

Description

Uses a device to capture the result of an expression (expr) that produces a plot. If default_device() is used, custom fonts (specified through font_spec()) are guaranteed to work, as long as one of either the showtext or ragg package(s) are installed.

Usage

thematic_save_plot(
  expr,
  device = default_device(),
  filename = tempfile(fileext = ".png"),
  ...
)
default_device(type = c("png", "svg", "pdf", "tiff", "jpeg"))

Value

thematic_save_plot() returns the filename of the produced plot and default_device() returns a graphics device function.

Arguments

expr

an expression that produces a plot.

device

a graphics device to use for capturing the plot.

filename

a filename for the produced plot. The file extension should match the relevant device.

...

arguments passed along to the graphics device.
