[R] Warning message: cannot create HTML package index

[Leo]

I have set R_LIBS=~/R_lib as I don't have root access.

The following message shown up every time after installing a package:

  ......
  The downloaded packages are in
  	/tmp/RtmpBoIPoz/downloaded_packages
  Warning message:
  cannot create HTML package index in: tools:::unix.packages.html(.Library) 

Any ideas?
