R help - Mar 2007 - Problem with adding packages to default start-up list

After reading the help files (?Startup) and using 
RSiteSearch("defaultPackages"), I have been trying to add several
packages
to my default startup list using the following code:

local({
old<-getOption("defaultPackages")
options(defaultPackages=c(old,"lattice","RODBC")
})

Subsequently, when I query the default list using:

getOption("defaultPackages")

the list of packages I have added appears along with the standard defaults.  
However, when I restart R, none of these packages are loaded and they don't 
appear in the default list when it is queried again.  There's probably 
something simple I am missing and I am hoping that someone will (politely) 
point out where I've messed up.

I am running R 2.4.0 on a Windows 2000 PC.  Sys.getenv("R_USER")
returns the
location of my Rconsole in the "...My Documents" file, but my working 
directory is in the "...program files/R/R-2.4.0" directory, if that
helps.

Thanks for your assistance.

Where did you put this code?
It has a syntax error in the third line, which might be the issue (and 
whether you get an error depends on where you put it).  Once that is 
corrected this works for me in ~/.Rprofile.
