Hi John,

help("%in%") may be of use. However I don't see any overlap in your example.
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")
endProject<-as.POSIXlt("2007-12-31")
startProject<-as.POSIXlt("2006-12-01")
project <- as.numeric(endProject-startProject)
period <- as.numeric(endPeriod-startPeriod)
I see how to use intersect with numbers as in the example:
intersect(1:10,7:20)
%in% returns a logical vector indicating if there is a match or not, thus it is
not an option for us.
*Please, how could I pass the date in seconds to intersect?*
I know how to get system time in seconds, unclass(Sys.time()), but how could I
get endPeriod, startPeriod and so on, so forth, to pass this values to
intersect? It is the only way I can figure out to get a vector with the
intersecting period. It will be a huge vector in some cases, but I guess I
could get its size in anyway and to avoid to print out the values.
Thanks for your help,
Ricardo
