Hi all,
the problem is when you try to round.Posix an empty vector of dates
  
Please give a look to this code:
> data=seq(ISOdate(2001,1,1),by="day",length=3)
> data
[1] "2001-01-01 13:00:00 ora solare Europa occidentale"
[2] "2001-01-02 13:00:00 ora solare Europa occidentale"
[3] "2001-01-03 13:00:00 ora solare Europa occidentale"

this works:
> non.crasha=round(data[c(F,F,T)],"day")
> non.crasha
[1] "2001-01-04"


this (subsetting data with an empty set) crashes R on w2k
crasha=round(data[c(F,F,F)],"day")

these are infos about my R
