Save a plot as a .png — save

A wrapper for calling grDevices::png() then grDevices::dev.off(). Allows users to save a plot to a specified path. The preferred method for ggplot2::ggplot objects remains ggplot::ggsave(). However if you wish to use this function to save ggplot2::ggplot objects, print the plot as the last step of plot_code.

save_png(plot_code, path, width = 8, height = 6, units = "in", res = 600, ...)

Arguments

plot_code: code required to generate the plot, sandwiched in curly braces.
path: character(1) specifying path for where to save your plot, including file name.
width: the width of the device.
height: the height of the device.
units: The units in which height and width are given. Can be px (pixels, the default), in (inches), cm or mm.
res: The nominal resolution in ppi which will be recorded in the bitmap file, if a positive integer. Also used for units other than the default, and to convert points to pixels.
...: additional arguments are passed to grDevices::png().

Value

Invisibly, the path to saved plot.

Examples


save_png(
  {
    plot(x = 1:5)
  },
  path = file.path(tempdir(), "test_plot.png"),
)
