This is getting pretty convoluted.
The current behavior is consistent with the description at the top of
the help page -- it does not promise to stop evaluation once the first
non-TRUE is found.
Hm... we can read in the man page :
‘stopifnot(A, B)’ is conceptually equivalent to
{ if(any(is.na(A)) || !all(A)) stop(...);
if(any(is.na(B)) || !all(B)) stop(...) }
and this behavior does promise to stop at first non-TRUE value
without evaluation of the rest of conditions.
Sergueï.
