The following raises an error:
if (as.raw(1)) 1
# error: unimplemented type 'raw' in 'asLogical'
However, ?'if' says:
"
Arguments:
cond: A length-one logical vector that is not 'NA'. Conditions of
length greater than one are accepted with a warning, but only
the first element is used. Other types are coerced to
logical if possible, ignoring any class.
"
and the help page does not mention raw type arguments to 'if' at all.
The error above is in clear contradiction to the documentation. This might be a
flaw in the documentation, but the following succeeds:
ifelse(raw(1), 1, 0)
# 1
which suggests that the error above is a bug (i.e., the implementation fails to
convert raw to logical).
The same problem involves 'while':
while(as.raw(1)) break
# error: unimplemented type 'raw' in 'asLogical'
