Dear Guys..
Thank you very much for taking time to answer these questions.
I 'm running simple command directly on R console:
> corpus=tm_map(corpus,tolower)
giving this result:
The process has forked and you cannot use this CoreFoundation
functionality safely. You MUST exec(). Once and again.
tm and SnowballC installed.
Runing: R 3.0.3 GUI 1.63 Snow Leopard build (6660)
I tried restarting system, deleting start-up sw, but nothing. Your
help will be much appreciated.
Thank you. Rodrigo.
