R help - Apr 2013 - Question: how to convert raw to numeric

I know that there is a function to convert binary data to string named
rawToChar.but  I wander is there any similar function for "Integer"
and
"float".I need to read some binary file in "integer" and
"float" data.
I can do this job in this way: (as below)
first convert 4 byte raw to bits then pack bits back to "integer", but
it
not work for "float",I worry about the performance.

raw4 = raw_buffer[1:4]

bits = rawToBits(raw4)

packBits(bits, type = "integer")


Best wishes

Really hope to get your response

See ?readBin - works also with raw objects.
