Plot using preview instead of plotting to X device

uses ggsave to save a ggplot object to file and then opens a new device and displays it.

ggpreview(
  plot = ggplot2::last_plot(),
  filename = tempfile(fileext = ".png"),
  ...
)

Arguments

plot

Plot to save, defaults to last plot displayed.

filename

File name to create on disk.

...

Arguments passed on to ggplot2::ggsave

device: Device to use. Can either be a device function (e.g. png), or one of "eps", "ps", "tex" (pictex), "pdf", "jpeg", "tiff", "png", "bmp", "svg" or "wmf" (windows only). If NULL (default), the device is guessed based on the filename extension.
path: Path of the directory to save plot to: path and filename are combined to create the fully qualified file name. Defaults to the working directory.
scale: Multiplicative scaling factor.
width,height: Plot size in units expressed by the units argument. If not supplied, uses the size of the current graphics device.
units: One of the following units in which the width and height arguments are expressed: "in", "cm", "mm" or "px".
dpi: Plot resolution. Also accepts a string input: "retina" (320), "print" (300), or "screen" (72). Applies only to raster output types.
limitsize: When TRUE (the default), ggsave() will not save images larger than 50x50 inches, to prevent the common error of specifying dimensions in pixels.
bg: Background colour. If NULL, uses the plot.background fill value from the plot theme.
create.dir: Whether to create new directories if a non-existing directory is specified in the filename or path (TRUE) or return an error (FALSE, default). If FALSE and run in an interactive session, a prompt will appear asking to create a new directory when necessary.
