[R] zoo: merging aggregated zoo-objects fails

Dear all, I have several text files looking like this: 9063032 19700201 22:00 174.067 9063032 19700201 23:00 174.076 9063032 19700202 00:00 174.085 9063032 19700202 01:00 174.091 9063032 19700202 02:00 174.094 9063032 19700202 03:00 174.091 9063032 19700202 04:00 174.082 9063032 19

Hello Gabor, I just tried dput() and it seems that running aggregate deletes the following information from zoo objects: origin = structure(c(1, 1, 1970)) So before merging I added: chron(index(z),origin=c(1,1,1970))->index(z) which solves my problem. Is that behaviour of aggregate.zoo intended
