[R] out.format for chron

[Denis Chabot]

Dear R users,

Do you know of a way to precise an out.format for a chron object that  
would use numbers for months and yet 4 digits for the year?

I have tried out.format=c("d-m-year") (note the m instead of either  
mon or month) but got 27-Feb-1992.

Also, the help for chron tells us how to define an out.format when we  
create a chron object, but how can you change the out.format of an  
existing chron object?

Thanks in advance,

Denis
