[BlindRUG] Difficulties with the WriteR package.

[Godfrey, Jonathan]

Hello Shey,

Thank you for the comprehensive description of your troubles with WriteR.
I do know what the problem is. The file you have already been working on includes utf-8 characters. WriteR isn't ready to deal with them yet. You could open the Rmd file in notepad and re-save a new version that uses ANSI encoding. Look under "save as" for your options.

The one point I need clarification on is if you have the latest version of BrailleR and WriteR. I ask because you are running an older version of R (3.4.3). I recommend updating R before getting the latest version of BrailleR from CRAN. You should be able  to run the following commands:
  library(installr)
  updateR(TRUE)

and after starting a new session of R which will now be using the updated version:

  chooseCRANmirror(ind=1)
  install.packages("BrailleR")

You are successfully starting a new file and it is being rendered successfully. The second window says "done", but the other elements you provided show me it is an older version of WriteR. Installing the new BrailleR package will resolve this, and perhaps a few other things.

It is clear to me that to have made it as far as you have, that Python is playing nicely for you. That is usually the biggest hurdle so you're well on your way.

HTH,
Jonathan

Subject: [BlindRUG] Difficulties with the WriteR package.

Hello, greetings to all.
I was trying to use the WriteR application in the brailleR package as a way of working interactively with R markdown, but I am experiencing difficulties as follows:
1. First, I tried to open a document I have successfully rendered using rmarkdown::render, but got the following result: Unable to read C:\Users\shey Lontum\Documents\BRFSS.Rmd into editor because 'utf8'
codec can't decode byte 0x92 in position 538: invalid start byte

I guess my working directory can be guessed from the error message, including the name of the Rmarkdown file "BRFSS.Rmd".

So I just tried to open an empty Rmarkdown file usingthe command:
WriteR("NewR"), but the only thing I can find on the new window is some text on the first line that says "Starting new file" and nothing else. And when I try to render this file, I get a long message that
says:

"Render output goes hereDone
Caught error [Error 6] The handle is invalid for ['C:\\Program Files\\R\\R-3.4.3\\bin\\x64\\Rscript.exe', '-e', 'if (!is.element(\'rmarkdown\', installed.packages()[,1])){install.packages(\'rmarkdown\',
repos="https://cloud.r-" and ofcourse, now HTML file is created in the working directory.

Pls what can I do?
Thanks.
Shey.
