[BlindRUG] beginner's introduction and first question

[Jacques CELLOU]

Hello,
This is my first message on the list. I'm new to using R and its 
BrailleR package. I'm a student in Public Health. I'm French and, sorry, 
my English is pretty bad: I use translation software to write to you, 
which can give strange formulas.
My first question concerns Writer, for which I have a configuration 
problem...  that I haven't been able to solve for several days.
I'm using a version of Windows 11 and the current version of NVDA.
I think I've installed R, Python, WXPython and Pandoc correctly.

 > TestWX()
a window opens with the message:
It looks like the WX module is available. Close this window and start WriteR

However, the RTerm console displays (sorry, part of the message is in 
French)
):
Messages d'avis :
1: In shell(paste("python", system.file("Python/TestWX.py",  ... :
   l'exécution de 'python 
C:/Users/jacqu_p3krno8/AppData/Local/Programs/R/R-4.3.3/library/BrailleR/Python/TestWX.py' 
a échoué avec le code d'erreur 5
2: In .CannotSeeWxPython() :
   Python cannot see the necessary wx module.You need to get that fixed.


 > library(knitr)

 > library(rmarkdown)

 > WriteR("MySandBox.rmd")
WriteR opens correctly, but building the .rmd file in html fails with 
the message :
Render output goes hereDone
Caught error expected str, bytes or os.PathLike object, not NoneType for 
[None, '-e', 'if (!is.element(\'rmarkdown\', 
installed.packages()[,1])){install.packages(\'rmarkdown\', 
repos="https://cloud.r-project.org")};require(rmarkdown);rmarkdown::render("C:\\\\Users\\\\jacqu_p3krno8\\\\OneDrive\\\\logiciels\\\\R-EspaceDeTravail\\\\MySandBox.rmd",quiet=TRUE)'] 



Do you have any idea what's going on and what I need to do to make it work?
Thank you in advance,
Jacques
