aggregate.ts
Consider the following scrap of code:
> x<- ts(1:50,start=c(1,11),freq=12)
> y <- aggregate(x,nfreq=4)
> c(y)
[1] 6 15 24 33 42 51 60 69 78 87 96 105 114 123 132 141

What would y´all do with a quarterly dataset that contains one column for the period and one for the year. Do I have to convert it to one single date
