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

#' BRL.end
#' @title Generate and optimize a braille-embedded ready-to-print pdf file for swell form machine

#' @aliases BRL.end
#' @keywords BRL.end

#' @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.

#' @export BRL.end

#' @details
#' *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.

#' 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

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

#' @examples
#' BRL.begin()
#' hist(airquality$Ozone)
#' BRL.end()
#' # The braille ready-to-print pdf version will be created in your working directory. Print it out and run the swell touch paper through swell form heating machine.
