Dear all I try to make hourly average by cut() function, which almost works as *I* expected. What puzled me is that if there is only one item at the end of your data it results in NA.
Example will explain what I mean datum<-seq(ISOdate(2004,8,31), ISOdate(2004,9,1), "min") cut(datum[1370:1381],"hour", labels=F) [1] 1 1 1 1 1 1 1 1 1 1 1 NA cut(datum[1370:1382],"hour", labels=F) [1] 1 1 1 1 1 1 1 1 1 1 1 2 2 I do not understand why the last item in first call is NA. I found it only when there was a switch from DST to standard time as it coused a trouble in one of my functions and I found there is NA value where I did not expected it. I can make some workaround but can you please explain me why first call results in NA value at the end of a vector and if it is *intended* behaviour. If yes I can count with it in improvement of my function(s), if not I can make some temporary workaround. Thank you.
