1) Install R on USB stick:
   Start R installer (named something like (R-2.x.y-win32.exe).
   During installation:

   i) Select drive corresponding to USB stick for location to which R
      is to be installed (i.e. if USB stick is drive DRV, then install R
      to location DRV:\R-2.x.y).

   ii) Customize startup:
       a) select SDI, everything else per default
       b) may be necessary to select internet2 as internet connection
          if sitting behind a proxy (but it is also possible to do so
          later, i.e o.k. to use the default) 

   iii) Don't create a "Start Menu folder"
   iv)  Don't create desktop icon or registry entries

2) Create a short cut to Rgui.exe (located in
   DRV:\R-2.x.y\bin\Rgui.exe) and  move it to the top folder of the
   USB stick.  
   Optionally, rename short cut (e.g. Raffle Draw)
   
3) Start R using the short cut.

4) Select "Install package(s) from local zip files" from Packages menu:
   select RaffleDraw_1.y.zip (currently y=1, but may change) for installation.

5) Select "Install package(s)..." from Packages menu:
   select appropriate CRAN mirror, then select gWidgets and
   gWidgetsrJava to be installed. 
   quit R

   If this step does not work, then you are probably sitting behind a
   proxy.  In that case, go to the short cut that points to Rgui.exe,
   right click on the short cut and select properties from pop-up
   window; add "--internet2" to the target (i.e. the target should
   read something like "DRV:\R-2.x.y\bin\Rgui.exe --internet2").
   Click "Apply" and then "Ok" and try again.

6) Right-click on short cut and select properties from pop-up window;
   change entry for "Run:" from "Normal window" to "minimized".  Click
   "Apply" and then "Ok".  (Remove the "--internet2" option if it had
   been added)

7) Goto to the folder DRV:\R-2.x.y\etc and edit the Rprofile.site file
   located in that folder:
   add "library(RaffleDraw)" as last line (without the quotation marks)
   save file and quit

8) go to top folder of USB stick and double click on the short cut.
