[R] (a) R capacity and (b) sorting cases in R

[Dimitri Liakhovitski]

1. I have a .txt file that has no more than 10 variables and about 3.5
MILLION cases.
Can R handle so many cases or should I not even try?

2. How do I sort cases (e.g., alphabetically) in R and then save the
sorted results in a new file?

Thank you!
Dimitri
