[R] WriteBin problem

[Harutyun Khachatryan]

Dear R project officials,

I have found that in R 3.0.1 version "writeBin" function of "base" package might not work correctly. For command writeBin("100",raw()) it answers "31 30 30 00" the last double 0 is differs from http://www.branah.com/ascii-converter there ascii codes are "31 30 30". So is it normal having double 0-s after ascii codes and what it means? 

Thank you in advance.
Regards, Harutyun Khachatryan.
