[R] Installing RQuantLib on Win 7 64 Bit

[Santosh Srinivas]

Hello Group,

I am trying out RQuantLib on a 64bit Win 7 machine. But running into
installation errors

install.packages("RQuantLib")

Warning in install.packages("RQuantLib") :
  argument 'lib' is missing: using
'C:\Users\Tester\Documents/R/win64-library/2.11'
Warning: unable to access index for repository
http://www.stats.ox.ac.uk/pub/RWin/bin/windows64/contrib/2.11
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘RQuantLib’ is not available


Any help with this installation?

Thank you.
S
