[BlindRUG] Sharing Successful Braille Labelling Test

[JOOYOUNG SEO]

Hello Dr. Godfrey,

I am writing to share my test with you.

Today, I worked with my colleague to use braille font in R graphics and 
it was successful and an eye-opener.

I hope our findings could contribute to updating future BrailleR.

1. I downloaded this font 
<http://www.fontspace.com/philing/braille-normal> and installed it.

2. The following is the syntax I used to get the braille-labled histogram:

chooseCRANmirror(ind=1)

install.packages("extrafont")

library(extrafont)

data(airquality)

attach(airquality)

font_import(pattern="BRAILLE1.ttf", prompt=FALSE)

windowsFonts(A=windowsFont("Braille Normal"))

hist(Ozone, family="A")

----------

3. Problem and question:

A. I cannot save the graphic as PDF.

B. Do you think we can also get free grade2 braille font? This is grade1.

----------

Thank you.
   Best Regards,

        JooYoung
