Write Plots to a PDF

Given a list of plots, write all plots to a single pdf file containing one plot per page, and optionally save the graph layout as a csv file.

Usage

saveNetworkPlots(
  plotlist,
  outfile,
  pdf_width = 12,
  pdf_height = 10,
  outfile_layout = NULL,
  verbose = FALSE
)

Arguments

plotlist

A named list whose elements are of class ggraph. May also contain an element named graph_layout with the matrix specifying the graph layout.

outfile

A connection or a character string containing the file path used to save the pdf.

pdf_width

Sets the page width. Passed to the width argument of pdf().

pdf_height

Sets the page height. Passed to the height argument of pdf().

outfile_layout

An optional connection or file path for saving the graph layout. Passed to the file argument of write(), which is called with ncolumns = 2.

verbose

Logical. If TRUE, generates messages about the tasks performed and their progress, as well as relevant properties of intermediate outputs. Messages are sent to stderr().

Value

Returns TRUE, invisibly.
