See the above example. Is there a way to make 'drop=FALSE' as global
default, so that when I say 'tmp[,1]', R will treat it as
'tmp[,1,drop=FALSE]'?
Is there a way to set drop=FALSE globally?
No.
I can't remember to put
drop=FALSE to all the '[]'s. But this indeed causes some weird bugs
for me to figure out.
It would probably cause a lot more weird bugs if the behavior of [ depended on
a global option.
