R help - May 2006 - read.table with data in specific formats

Dear R Users

 Does anyone know how to read a text with a specific format?   I know that has
to do with two functions: read.table and sprintf but not sure how to put them
together.   Say that I have a text file called "data.txt", and I would
to read it according with  "%.14f %.10f %2.5f", which includes three
columns.

Thank you very much.

"read.table" segments rows by separators, not by format of entry.

Suppose your "data.txt" is like:
1.00 2.01 3.003
4.10 5.22 6.333
7.22 8.88 9.99

Then
> read.table("data.txt", sep = " ")
