Hi Petr,
The solution you shared worked though it does not show any decimal values.
The output is
Group.1 x
1 1/1/2015 309450
2 1/10/2015 332780
Instead of mean i used sum & i think that should be fine.
aggr<-aggregate(retail$weight,list(retail$ship.date),function(x)
round(sum(x,0)))
That adds all the elements of x and zero and then rounds it
So if i change above code to x,1 it changes values to
That will add all the elements of x and unity and then round it. Notice
that your result has increased by unity each time.
I think you meant to write round(sum(x), 0) or round(sum(x), 1) as the
case may be
Group.1 x
1 1/1/2015 309451
2 1/10/2015 332781
Thanks, Shivi
