Save a VISTA plot object to disk — save_vista

Saves plot objects returned by VISTA plotting functions to file. Supports both ggplot-like objects (saved via ggplot2::ggsave()) and ComplexHeatmap objects (Heatmap / HeatmapList) saved via graphics devices.

Usage

save_vista_plot(
  plot,
  file,
  width = 8,
  height = 6,
  units = "in",
  dpi = 300,
  device = NULL,
  ...
)

Arguments

plot: A plot object. Typically ggplot, patchwork, Heatmap, or HeatmapList.
file: Output file path.
width: Plot width.
height: Plot height.
units: Units for width and height. One of "in", "cm", "mm", or "px".
dpi: Resolution for raster outputs.
device: Optional graphics device (e.g. "png", "pdf"). If NULL, inferred from file extension (defaults to "png" when missing).
...: Additional arguments passed to ggplot2::ggsave() for ggplot-like objects.

Value

Invisibly, the normalized output file path.

Examples

v <- example_vista()
p <- get_pca_plot(v)
out_file <- tempfile(fileext = ".pdf")
save_vista_plot(p, file = out_file, width = 7, height = 5, units = "in")
