R help - May 2012 - how disable the Error massage in read.table() " no lines available in input"

Dear Researchers,

I am looking a way to disable the Error massage in read.table() as warn TRUE in
readLines(), when the lines are empty

Error in read.table(con, header = F, sep = " ", nrow = n) :
  no lines available in input

thanks for all suggestions
Gianni

Hello,

Apparently this is a follow-up from  an earlier post.
I had answered but a misplaced comma in the subject line started another 
thread, that you haven't read.
My original answer is in

http://r.789695.n4.nabble.com/Re-Problem-to-resolve-a-step-for-reading-a-large-TXT-and-split-in-several-file-td4630242.html

As for your question, see the error trapping functions help pages.

?try
?tryCatch

And, in readLines the correct option would be ok = TRUE, warn = TRUE is 
about an end of text marker.

?readLines

Hope this helps,

Rui Barradas
