Sorry, I don't follow. I routinely work with objects in my workspace that are much larger than 100MB, so I don't think I understand what you mean here. Is R running out of memory, or is your computer running out of memory? If it's the former, are you running 32bit or 64bit R? > Not sure > if there are any other limitations on variable length and source file length. > So my question is > > what are the limitations of variable name length and the source file length > in R?
