In ClaraMarquardt/ehR: A collection of R functions designed to facilitate the interaction with and analysis of EHR data.

Description

Given a list of ggplot objects - arrange the plots on a page (with a specified number of plots columns/rows per page) and save as a (multi-page) PDF

Usage

generate_pdf(ggplt_list, ncol_plot = 3, nrow_plot = 3, output_path,
  output_file, orientation = "vertical", share_legend = FALSE,
  quiet = FALSE, height_plot = NULL, width_plot = NULL,
  height_overall = NULL, width_overall = NULL)

Arguments

ggplt_list	List of ggplot objects (list - ggplot).
ncol_plot	Number of plot columns on each page of the final PDF (integer) [default: 3].
nrow_plot	Number of plot rows on each page of the final PDF (integer) [default: 3].
output_path	Path where the final PDF is to be saved ("...../") (character).
output_file	Namer under which the final PDF is to be saved ("...pdf") (character).
orientation	Page orientation of the final PDF (character - "vertical"/"horizontal") [default: "vertical"].
share_legend	Whether or not all plots on a page are to share one legend (logical - TRUE/FALSE) [default: FALSE].
quiet	Whether to print status updates as individual pages are generated (logical - TRUE/FALSE) [default: FALSE].

generate_pdf(ggplt_list=plot_list, ncol_plot=3, nrow_plot=2, 
 output_path="", output_file="merge_pdf_test", orientation="horizontal", 
 share_legend=FALSE, quiet=FALSE) 
}
