Save a plot with publication-ready defaults

A convenience wrapper around ggplot2::ggsave() with sensible defaults for figures in papers and reports: a moderate size, 300 dpi, and the output directory created if needed. The device is inferred from the file extension.

Usage

save_plot(
  filename,
  plot = ggplot2::last_plot(),
  width = 7,
  height = 4.5,
  units = "in",
  dpi = 300,
  ...
)

Arguments

filename: Output file path. The extension sets the device (e.g. .png, .pdf, .tiff).
plot: The plot to save; defaults to the last plot drawn.
width, height: Dimensions.
units: Units for width and height.
dpi: Resolution for raster devices.
...: Passed to ggplot2::ggsave().

Value

The filename, invisibly.

Examples

p <- scatter_trend(crop_yield, fertiliser, yield)
tmp <- file.path(tempdir(), "yield.png")
save_plot(tmp, p)
