R help - Jun 2013 - Bytes to Numeric/Float conversion

Is there any packages available in R, that can convert Bytes array to Float.
Using rJava we can do it. But it is kind of slow. Is there any R
specific packages.
I am having problem converting my bytes array to floating point.
Could any one help me with this problem.

Thanks
Bikash

There is a raw data type that is designed to hold bytes than can be indexed.

?raw

`scan` can read files of type raw

?scan

Actually I am using rJava, running some map-reduce using R.
The data send is in bytes, but actually it is floating-point number.

On R side, I need to convert this byte into Float. But I couldn't find any
function.
I am try using rawToChar() which convert into character. And later on
as.double to convert it.

But it is not giving the exact value.
Could any one help me out.
