Hi
I have a few problems with tail/head when applied to multiple time
series. I'm not sure as whether I did not understand the function or
whether it correspond to an unexpected behavior.
When head(a,n) is applied on data.frame or matrix, it returns a
data-frame or matrix with first n obs of *each* variable. When applied
to a mts object, it returns first n obs of *first* variable only, not
of all... The same for tail(). See:
head(freeny)
###mts object
head(EuStockMarkets)
#is equivalent to:
head(EuStockMarkets[,1])
I guess it comes from absence of a head method for mts. Does it seem
reasonable to have also a head.mts or did I misunderstand something?
Thanks
