Plot general structure and connectivity statistics for a filtered GRN

Description

This function generates graphical summaries about the structure and connectivity of the TF-peak-gene and TF-gene graphs. These include, distribution of vertex types (TF, peak, gene) and edge types (tf-peak, peak-gene), the distribution of vertex degrees, and the most "important" vertices according to degree centrality and eigenvector centrality scores.

Usage

plotGeneralGraphStats(
  GRN,
  outputFolder = NULL,
  basenameOutput = NULL,
  plotAsPDF = TRUE,
  pdf_width = 12,
  pdf_height = 12,
  pages = NULL,
  forceRerun = FALSE
)

Arguments

GRN	Object of class GRN
outputFolder	Character or NULL. Default NULL. If set to NULL, the default output folder as specified when initiating the object in link{initializeGRN} will be used. Otherwise, all output from this function will be put into the specified folder. We recommend specifying an absolute path.
basenameOutput	NULL or character. Default NULL. Basename of the output files that are produced. If set to NULL, a default basename is chosen. If a custom basename is specified, all output files will have the chosen basename as file prefix, be careful with not overwriting already existing files (if forceRerun is set to TRUE)
plotAsPDF	TRUE or FALSE. Default TRUE.Should the plots be printed to a PDF file? If set to TRUE, a PDF file is generated, the name of which depends on the value of basenameOutput. If set to FALSE, all plots are printed to the currently active device. Note that most functions print more than one plot, which means you may only see the last plot depending on your active graphics device.
pdf_width	Number. Default 12. Width of the PDF, in cm.
pdf_height	Number. Default 12. Height of the PDF, in cm.
pages	Integer vector or NULL. Default NULL. Page number(s) to plot. Can be used to plot only specific pages to a PDF or the currently active graphics device.
forceRerun	TRUE or FALSE. Default FALSE. Force execution, even if the GRN object already contains the result. Overwrites the old results.

Value

The same GRN object with no changes. The results are output to a file.
