How much memory do you have on this machine? Are you using 32-bit R and/or OS? Are you able to load a smaller number of files (~5)?

Answer 1

[Antonio R. Franco]

It seems that you need a computer with more RAM resources Hoping you are not using a 32bits R, since it can allocate less memory than a 64 bits R

I have used 64bit R and also my window is 64bits.. But still facing this problem. :(

[Antonio R. Franco]

Still is needed to be known the amount of RAM memory set in your computer. What operative system are you using ?

In addition, run this commands into R

memory.limit() # It will provide the memory available

And read this article

Suppose you need 2000 memory size, I think you could simply run this code memory.limit(size=2000) and then run your script(also you could give more size to your memory size), In my case I set my machine memory size to 190000
