Not as far as I can tell:
what: Either an object whose mode will give the mode of the vector
to be read, or a character vector of length one describing
the mode: one of ‘"numeric"’, ‘"double"’, ‘"integer"’,
‘"int"’, ‘"logical"’, ‘"complex"’, ‘"character"’, ‘"raw"’.
Note: Either...or...
I.e., you can use a character string (==vector of length one)
readBin(zz, "int", 8, size = 1)
and you can use an object of the desired mode
readBin(zz, integer(), ...) or equivalently readBin(zz, 0L, ...)
but there is no implication that each of the possible character strings have a corresponding function. It is not clear why we allow both "int" and "integer" here, but there is no reason to expect int() to exist.
