R help - Jul 2012 - memory size

Dear R community,

I'm running "a mlogit" function with a very large data set. Since
the data
size is so large, I got the Error:

Error: cannot allocate vector of size 5.4 Mb
In addition: Warning messages:
1: In mapply("*", X, P, SIMPLIFY = FALSE) :
  Reached total allocation of 16340Mb: see help(memory.size)
2: In mapply("*", X, P, SIMPLIFY = FALSE) :
  Reached total allocation of 16340Mb: see help(memory.size)
3: In mapply("*", X, P, SIMPLIFY = FALSE) :
  Reached total allocation of 16340Mb: see help(memory.size)
4: In mapply("*", X, P, SIMPLIFY = FALSE) :
  Reached total allocation of 16340Mb: see help(memory.size)

I'm using win7 and my computer has 16G memory. Is there a way that I can
make R use the memory more efficiently?

Thanks!
Gary

There are many possibilities, but they all begin with reading the posting guide
and following the recommendations therein so we don't have to guess what
your actual configuration is.  However, since your first task is to read, you
might consider reading the FAQs on memory use and Windows specifically so you
can ask more specific questions.
