I'm relatively new user of RMD and I've tried to edit some programmation coding with it to make interactive analyses reports.
I'm using french language for commenting the codes and outputs where accents on a and e letters are very common...
I've starting my program using:
and the special letters are transformed by different characters. Also when reopenning my RMD file on an other session the special characters are changed again.
I went to the net and found that tinytex package could help but the following command did not change anything.
options(tikzDefaultEngine = "xetex")
Do you have a specific recommendation / advices to keep the specific speaking language punctuation on both RMD files when saved as well as for editing the pdf and html files?
many thanks for your advices...
