Save a UMG diagram to a file

Renders a UMG to a graphics file (PDF, PNG, or SVG), or writes code for one of the export backends. The output format is taken from the file extension: .pdf/.png/.svg produce graphics, .tex/.tikz produce TikZ source, and .dot/.gv produce Graphviz DOT source. Graphics may be produced with either the base grid renderer (default) or the ggplot2 backend. Graphics dimensions are in inches.

Usage

umg_save(
  model,
  file,
  width = 6,
  height = 4.5,
  res = 300,
  theme = umg_theme(),
  backend = c("grid", "ggplot"),
  ...
)

Arguments

model

An object of class umg.

file

Output path; the extension (.pdf, .png, .svg, .tex/.tikz, .dot/.gv) selects the format.

width, height

Dimensions in inches for graphics devices.

res

Resolution in dpi for PNG output.

theme

A umg_theme for graphics output (see umg_theme()).

backend

Graphics backend for raster/vector output: "grid" (default) or "ggplot".

...

Passed to plot.umg() / umg_ggplot() (graphics), umg_to_tikz() (TikZ), or umg_to_dot() (DOT).

Value

The path file, invisibly.

Examples

umg_save(umg_factor("F", paste0("y", 1:4)),
         tempfile(fileext = ".pdf"))
umg_save(umg_irt("2PL"), tempfile(fileext = ".tex"))
umg_save(umg_irt("2PL"), tempfile(fileext = ".dot"))
