Just surround any graphic object between two functions brl_begin() and
brl_end(). The graph will be created in PDF format in your current
directory, with all text being presented using a braille font. See more
details in the example section below.
You can install the latest development version as follows:
if(!require(devtools)) {
install.packages("devtools")
}
devtools::install_github('jooyoungseo/tactileR')You can install the released version of tactileR from CRAN with:
install.packages("tactileR")| Argument | Description |
|---|---|
| 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), and “TIMES” for “times.ttf” (Times New Roman). Default is set to “BRL”. |
Note: This function optimizes for both 1111 and 118.5 swell touch papers. When printing a generated braille pdf, just remember two things:
- check “Fit” in the print dialog box (the shortcut key is ALT+F).
- 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.
- A short YouTube video will help you to understand how this function can be employed in conjunction with Swell form machine.
Nothing within the R session, but a pdf file will be created in the user’s working directory.
# Loading tactile package:
library(tactileR)
# Create tactile graphic by surrounding between two functions like below. The arguments used in this example are all given by default:
brl_begin(file='tactile.pdf', pt=11, paper='special', font='BRL')
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.library(tactileR)
x <- rnorm(100)
brl_begin('test.pdf')
boxplot(x)
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.Note: Histogram and boxplot are just examples. You can feed any graphic object through the functions. barplot, interaction plot, regression plot, network graph, wordcloud, etc.
Currently this package does not support braille translation. This means you cannot embed any special symbols, math symbols, contracted braille, and non-roman alphabet characters. This issue will be addressed later by employing Liblouis translator.
