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
> y
Error in rep.int("", start.pad) : invalid number of copies in rep.int()
> tsp(y)
[1] 1.833333 5.583333 4.000000
So we can aggregate into quarters, but we cannot print it using
print.ts Even if print.ts cannot line the series into columns as it
normally does for quarterly data, we would expect it to behave as it
does when we aggregate into thirds.
> y3 <- aggregate(x,nfreq=3)
> y3
Time Series:
Start = 1.83333333333333
End = 5.5
Frequency = 3
[1] 10 26 42 58 74 90 106 122 138 154 170 186
And don't tell me that the aggregating a monthly series into quarters
makes no sense!! (see response to Bug 9798).
