In sjystu/SwellR: Converting an R Graphical Output into a Braille Ready-to-Print PDF File for Visually Impaired R Users Optimized for Swell Form Machine

Description

The first argument to this function must be a call to create a graph, such as a histogram. Instead of opening a new graphics device, the graph will be created in a pdf file, with all text being presented using a braille font.

Usage

BRL.begin(file = "tactile.pdf", pt = 11, paper = "special",
  font = "BRL")

Arguments

file	A character string giving the filename where the image is to be saved. The default file name is "tactile.pdf" if not given.
pt	Numeric value specifying braille font size for a created file. Default is 11.
paper	Character value setting paper size of output pdf file. Default is "special".
font	Character value for font family. Available options include "BRL" for "BRAILLE1.ttf" (Braille Normal) and "SWL" for "Swell-Braille.ttf" (Swell Braille). Default is set to "BRL".

Details

BRL.begin

*Note*: This function optimizes for both 11*11 and 11*8.5 swell touch papers. When printing a generated braille pdf, just remember two things: 1. check "Fit" in the print dialog box (the shortcut key is ALT+F). 2. Check "Landscape" in the print dialog box as well. * For boxplot, you do not need to check the "Landscape," just leave it as a "Portray." However, please check the "Fit" all the time. Information: If you are not familiar with what swell form machine is, please refer to [this web site](http://www.americanthermoform.com/product/swell-form-graphics-ii-machine/). A short Youtube video will help you to understand how this function can be employed in conjunction with Swell form machine: https://www.youtube.com/watch?v=ClI555l4Z1M

Value

Nothing within the R session, but a pdf file will be created in the user's working directory.
