[R] memory check

[Michael Griswold]

I'm working on R1.1.1 and was wondering if there is a way to check how 
much memory an object would require, a.k.a. a way to check whether the 
object you'd like to create is going to exceed the heap memory 
available?

 Something to the effect of:

  if ( memorycheck(object) > vsize ) { don't create object }
  else { create object }

 Thanks in advance for any help,

  Michael Griswold
