do not work if the index entries in ‘order.by’
are not unique
In either case, I am missing the "time" component. Where I am going wrong?
Thanks,

Is it a bug or a rule that for any function, placing of it's arguments matter?
Thanks,

Your tz argument has been passed as an argument of head. You want

Thanks Gabor for pointing to my old version. However I got one more question
why the argument tz="" is sitting there? As you are not passing any explicit
value for that, I am assuming it is redundant. Without any tz argument, I
got following:
head(read.zoo(file="f:/dat1.txt", header=T, sep=",",

index = list(1, 2)

called with two arguments
FUN(column1, column2)

I have compared "dat11" and "x" using str() function, however did not find
drastic difference:
> str(dat11)
‘zoo’ series from 2010-10-15 13:43:54 to 2010-10-15 13:49:51
Data: num [1:7, 1:4] 73.8 73.8 73.8 73.8 73.8 73.8 73.7 73.8 73.8 73.8 ...
- attr(*, "dimnames")=List of 2
..$ : chr [1:7]
r previous file? In help, it is given
that:"If FUN is specified then read.zoo calls FUN with the index as the first
argument". I really could not connect your syntax with help.

Dear all, I have following 2 zoo objects. However when I try to merge those 2
objects into one, nothing is coming as intended. Please see below the objects
