[R] extracting rows and columns from a big matrix

Hi everybody.

I didn't write the code because of it is very long one, but I have decided to enclose it in a text file. It is divided in:

1) the whole code that doesn't work

2) Seven parts which code was splited in and working

I am using R 64-bits release running on Windows 7. Sure, I was copy-and-pasting code and executing all operations using Notepad++. Besides, I am newbie using R and I am employing R Studio to develop this tests. I am not sure what are you meaning when you recommend me source(). Are you saying regarding R or text editor? I have read something about problems with encoding and for this reason I have save the file in UTF-8 as well. I gues this is a problem related to length of code line because when I have divided the whole code into several parts, some of them didn't work till I shortened them.

Sorry so much for all inconveniences.
