[R] Building a vector of dates between extreme dates

[v.demartino2@virgilio.it]

I would like to build a data.frame with a column of POSIXct dates orderly
differing  one day per row exactly, that is:

Data            dato1
01/06/2005   .......
02/06/2005   .......
..............
29/06/2005   ........
30/06/2005  etc


giving the extreme dates 01/06/2005 & 30/06/2005.


How  can i obtain this result?
