save_png: Save a plot as a .png

In dzhang32/rutils: `rutils` is a home for my commonly used R utility functions

Description

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.

Usage

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"),
)
