invisible(gc())

worked perfectly. Thanks Jeff.

@ Josh: I know how to toggle showing/hiding command echos, but I
haven't figured out how to toggle on/off any printed output.

Use "results=hide" as an Sweave option, e.g.

<<echo=FALSE, results=hide>>=
gc()

I must be reading the help file for gc() wrong. I thought it said that
gc(verbose=FALSE) will run the garbage collection without printing the
Ncells/Vcells summary. However, this is what I get:

gc(verbose = FALSE)
        used (Mb) gc trigger  (Mb) max used  (Mb)
Ncells 267097 14.3     531268  28.4   531268  28.4
Vcells 429302  3.3   20829406 159.0 55923977 426.7

I'm embedding this in an Sweave/TeX file, so I *really* can't have
this printing out. Suggestions other than manually editing the TeX
file?
