[R] reading in "!" - delimited file

[Dimitri Liakhovitski]

I have to read in a file that is "!" delimited.
Would it be correct to use the following syntax:

Data<-read.delim(file.choose(),sep="!")

Or would it be wrong? I am asking rather than trying it just because I
have 3.5 million cases to read in.

Thank you!
Dimitri
