i'd suggest to remain as close as possible to the usual behavior of R. there
you have three options:
q() # meaning 'save="default"', will ask you whether workspace
# should be saved; this is what RKWard currently does as well
q("yes") # will quit R while automatically saving the workspace;
# equivalent to what thomas was suggesting above
q("no") # will quit R and discard the current workspace, no questions asked
RKWard should just behave the same way, making it possible to set the 'save'
argument in q()/quit(), which it currently doesn't use (you don't get an error
if you set 'save' but in effect "default" remains hardcoded).
if RKWard respected the use of 'save' like vanilla R, then even without
changing the UI you could already customize the default closing behavior by
putting something like
formals(q)$save <- "no" # or "yes"
in the options input field in RKWard's R backend configuration. to make this
even more accessible, a dropdown menu could be added to that dialog, like
"save current workspace when RKWard is closed"
with options
- "always save and restore automatically" # save="yes"
- "always ask" # safe="default"
- "never save and restore automatically" # save="no"
and thereby set the formals like above, which i think is the most straight
forward way of doing this. because you can then still overwrite the formals
for the current session in a script or the console, which is what you find in
forums when you search for this R problem online.
