[BlindRUG] BRLThis() Question

[JooYoung Seo]

  Hello Dr. Godfrey,

  I have installed MikTex and tried again, but unfortunately, the issue was
not resolved.

On the other hand, I was able to successfully produce pdf with braille font
embedded, using the following personal script which is from my colleague.

  Please advise me how I can produce pdf like this using BRLThis
functionality as well.

  Our script is as follows:

 

##I assume you have already Braille Normal font and GhostScript installed in
your Window machine.

#Sys.setenv(R_GSCMD="C:/Program\ Files/gs/gs9.16/bin/gswin64c.exe")

 

library("extrafont")

 

# since you already have the font installed on the system, you don't need
the following

#font_import(pattern="BRAILLE1.ttf", paths="C:/Users/Admin/Downloads/fonts",
prompt=FALSE)

 

# the following enable PDF files to use the installed fonts

loadfonts()

 

# produce the PDF

pdf("output.pdf")

 

par(cex=1.2, cex.main=1.2, cex.lab=1.2, cex.axis=1.2, mar=c(5,5,3,2),
family="Braille Normal")

 

#Sample Graph

attach(trees)

hist(Volume, probability=TRUE pch=20)

lines(density(Volume), col="black", pch=20)

 

dev.off()

detach(trees)

# embed the font

Sys.setenv(R_GSCMD="C:/Program\ Files/gs/gs9.16/bin/gswin64c.exe")

embed_fonts("output.pdf")

# code ends here

Appreciatively,

 

       JY

Hello,

 

The BRLThis() functionality is quite experimental at this stage and we need
to work out what problems will limit its usefulness.

 

With respect to your error message, ghost script is software outside of R
that must be installed. It may be installed as part of LaTeX installation
such as miktex. You may need to install separately though. This will add the
external tool that adds any font to a pdf document. 

 

I'm away from my embossers for the next three weeks but will be monitoring
email and can try a few things or make suggestions.

 

Good luck,

Jonathan

  Hello List,

  I am very happy that we now have BrailleR version 0.22.0 

with incredible functions updated. I would like to express heartfelt
gratitude to Dr. Godfrey and other contributors for continuous updates.

  BRLThis(), one of the new functions, was what I really wanted to have in
R.

  I, however, am not able to use this feature for some reason. I am seeking
a solution.

  The below are my commands and the results:

----------

##My Commands:

with(airquality, BRLThis(hist(Ozone), "Ozone-hist.pdf"))

 

##Result:

Error in embedFonts(file = file, format = format, outfile = outfile, options
= paste(paste("-I", :

GhostScript was not found>

----------

  Any help would be greatly appreciated.

  Best Wishes,

 

       JY
