[R-SIG-Finance] How to change the way R format his output ?

[pierre8r-list at yahoo.fr]

Hi,

I try to :
Load 1 minute quotes from http://www.metaquotes.net/ into R.
Compute 15 mns quotes, 1 hour, daily quotes, etc. with R from 1 mn quotes.
Write to files these quotes.
Compare quotes from http://www.metaquotes.net/  with quotes from R, with Winmerge ( http://winmerge.org/ ), I compare directories.

How to change the way R format his output, and than Winmerge will not show any difference between the two files ?
