> sessionInfo()
R version 2.8.0 (2008-10-20)

locale:
LC_COLLATE=English_United States.1252;LC_CTYPE=English_United States.1252;LC_MONETARY=English_United States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252

Loading required package: fGarch

Loading required package: timeSeries
Loading required package: fBasics

I wonder whether this is intended.
