I figured out how to use quotes and parentheses when using Rscript -e (on a
bash shell):
Rscript -e write\(1,\"a.txt\"\)
--> Question 1: why do the parentheses need to be escaped in the shell?
(More a shell than an R question)
Then I figured out how to use quotes and parentheses when calling Rscript
through system:
system('Rscript -e write\\(1,\\\'a.txt\\\'\\)')
--> Question 2: why exactly is it necessary to use double and triple
escapes? I kinda understand it, but not completely.
Thanks for your insights!
