Thanks for the tips! 

Looking over the discussion I realized I
might have been unclear. What I would like to do is download a *large*
number of values for a certain date. I understood how to do download
data for a specific stock, but any idea as to how I could download
values for all (or a sample of) companies for a specific date :-)?

something like...
 yahooSeries(symbols = c("ALL"), from = NULL, to = NULL, 
    nDaysBack = 365, quote = c("Open", "High", "Low", "Close", "Volume"), 
    aggregation = c("d", "w", "m"), returnClass = c("timeSeries", "ts", 
    "matrix", "data.frame"), getReturns = FALSE, ...) thanks,

it's the fBasics *package*; a library is something (actually
more than one thing!) different!

you mean the maintainer of the *package*

the function is (now) called  keystatsImport() and is part of
'fCalendar' -- which is automatically required from package
'fBasics'.
help(keystatsImport) contains several examples, unfortunately
explicitly not available through example(), but I can
successfully execute all of them -- and they do work, including
the yahooImport() one.
