[Rd] Reading an "unsigned long long" using R readBin()

Sorry for the simple question, but I am trying to read an "unsigned long long" using the R readBin() function. Can someone point me in the right direction, or am I better off using C for such things? The file that I am reading will have been produced on the same machine that is doing the reading.

[Rd] readBin differences on Windows and Linux/mac

I have been trying to use the gunzip function in the R.utils package. It opens a connection to a gzfile, uses readBin to read from that connection, and then uses writeBin to write out the raw data to a new file. This works as expected under linux/mac, but under Windows, I get: Error in readBin(i
