Save a DAG plot to file — save

The function opens the appropriate graphics device based on the file extension (.tiff, .tif, or .png), renders the plot, and closes the device to ensure the file is properly written. Resolution is fixed at 300 DPI for publication quality output, and dimensions are specified in centimeters.

Usage

save_dag(path, plot, width = 50, height = 25)

Arguments

path: Character string specifying the output file path, including the filename and extension (e.g., "figure.tiff" or "output.png").
plot: A plot object to save. Must support printing via `print()` method (typically ggplot2 objects or grid grobs).
width: Numeric value specifying the plot width. Default is 50.
height: Numeric value specifying the plot height. Default is 25.

Details

This is a convenience wrapper around R's base graphics devices (tiff and png) that standardizes resolution settings to 300 DPI, which is suitable for publication-quality figures. Dimensions are specified in centimeters for consistency with typical figure sizing conventions.

Examples

# Basic usage - save a ggplot as TIFF (extension determines format)
library(ggplot2)
p <- ggplot(mtcars, aes(x = wt, y = mpg)) +
  geom_point()
save_dag("my_plot.tiff", p, width = 20, height = 15)
#> agg_record_1aef32063771 
#>                       2 

# Save as PNG automatically from extension
save_dag("my_plot.png", p, width = 20, height = 15)
#> agg_record_1aef32063771 
#>                       2
