Thanks Ista!
Indeed this is the workaround I had found, but not very practical as it
fails on univariate series, so you should know before which class is the
object... I feel a head.mts would make sense, or did I misunderstand
something?
Thanks!

Hi Mat,
You might be able to use the matrix method to get what you want.
head.matrix(EuStockMarkets)

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
