Save Insper Plot

Source: R/utils.R
save_insper_plot.Rd

Enhanced ggsave with institutional defaults and ragg device support

Usage

save_insper_plot(
  plot,
  filename,
  asp_ratio = 1.618,
  width = height * asp_ratio,
  height = 8,
  dpi = 300,
  device = NULL,
  unit = "cm",
  ...
)

Arguments

plot

ggplot object

filename

File name

asp_ratio

Aspect ratio (width / height). Default is the golden ratio (1.618). Used only when width is not supplied directly.

width

Plot width in inches

height

Plot height in inches

dpi

Resolution

device

Graphics device to use. If NULL (default), automatically uses ragg::agg_png() for PNG files when ragg is installed, otherwise falls back to ggplot2 defaults. You can override by passing a device function.

unit

Units for width and height. Default "cm". Passed to ggsave.

...

Additional arguments passed to ggsave

Value

The file path of the saved plot (invisibly), as returned by ggsave.

Details

This function automatically uses the ragg device for PNG output when available, which provides better font rendering and eliminates DPI issues. Install the ragg package and set the RStudio backend to AGG for best results.
