Hi,
It's surprising that stopifnot() keeps evaluating its arguments after
it reaches the first one that is not TRUE:
> stopifnot(3 == 5, as.integer(2^32), a <- 12)
Error: 3 == 5 is not TRUE
In addition: Warning message:
In stopifnot(3 == 5, as.integer(2^32), a <- 12) :
NAs introduced by coercion to integer range
> a
[1] 12
The details section in its man page actually suggests that it should
stop at the first non-TRUE argument:
‘stopifnot(A, B)’ is conceptually equivalent to
{ if(any(is.na(A)) || !all(A)) stop(...);
if(any(is.na(B)) || !all(B)) stop(...) }
Best,
H.
