I have a script which loads

library(XLConnect)
wb <- loadWorkbook("wbname")

the code works without errors when run from ESS which uses
R version 3.0.1 (2013-05-16) -- "Good Sport"
Copyright (C) 2013 The R Foundation for Statistical Computing
Platform: i386-w64-mingw32/i386 (32-bit)

But fails when run from Rscript
which Rscript
C:\Program Files\R\R-3.0.1\bin\i386\Rscript.EXE

Rscript updatevols.R
