[R] memory usage

[Setzer.Woodrow@epamail.epa.gov]

Does the following indicate that I have a memory leak?

> gc(TRUE)
Garbage collection 22891 = 21012+1557+322 (level 2) ...
483257 cons cells free (59%)
11.0 Mbytes of heap free (82%)
         used (Mb) gc trigger (Mb)
Ncells 334906  9.0     818163 21.9
Vcells 309342  2.4    1746173 13.4
> memory.size()/1024/1024 ## in MB
[1] 643.8978
> sum(sapply(ls(all.names=TRUE),object.size))
[1] 1776
> memory.limit()/1024/1024
[1] 600

I was repeatedly using try(eval(substitute(nlme(..)))), with lots of error
aborts from nlme.
