R help - Jan 2010 - new R package. How to hide data file

Dear R community,
I'm in the process of writing a package.

One of the functions reads a whole ascii file, full of data:
> SYMINFO <-
scan("/file/full/of/data.txt",what="character",sep="\n",quiet=TRUE)
SYMINFO is now an array character with roughly 14000 elements.

I thought the best way to use this file in the package was to list it, together
with the rest of
useful functions, in the list= field of package.skeleton. This way, a
"SYMINFO.rda" is created in
the data directory of the new package. It can, then, be used by all functons
needing it through
a 

data(SYMINFO)

line. I have created and installed the package and things work.

But I would like to make SYMINFO invisible to users. If I call SYMINFO as
.SYMINFO, the functions needing
this bit of data do not work anymore, even if I replaced 

data(SYMINFO)

with

data(.SYMINFO)


Does anyone have ideas why this is happening? Would you handle the whole process
differently?


Kind regards,

J
