Not yet. I'll keep trying.
Please, what format string must I pass to strptime to get the date as a
number? Thanks.

OK. Please, how do I force the select directory window to pop-up after
selecting a given repos and without restarting R?
When I submit install.packages("zoo", dep = TRUE) for the first time
after R starts, I am required to select a mirror. But this doesn't
happen in the next install command at
Select a different mirror until you find one that works for you.

hi: I don't know if it's the best way but one way is to use an
POSIXct object. ( you can convert using as.POSIXct(

exactly,
Try this:

You are right! I've choosen an example where the intersection is 0. But we
could consider this other case...
endPeriod<-as.POSIXlt("2008-09-30")
startPeriod<-as.POSIXlt("2007-10-01")
endP

Hi all,
Please, how could I calculate the time that two time segments has in
common? Is there any function to perform this calculation?
For instance, given four POSIXlt objects...
endPeriod<-as.POSIXlt("2008-09-30")
startPeriod<-as.POSIXlt("2007-10-01")
endProject<-as.POSIXlt("2007-05-31")
