# S3 method for xts
split(x, f = "months", drop=FALSE, k = 1, ...)Arguments

- k
number of periods to aggregate into each split. See Details.

further args to non-xts method
Details
A quick way to break up a large xts object by standard time periods; e.g. 'months', 'qaurters', etc.
endpoints is used to find the start and end of
each period (or k-periods). See that function for valid
arguments.
If f is not a character vector, the NextMethod is
called, which would in turn dispatch to the split.zoo method.
Value
A list of xts objects.
Note
aggregate.zoo would be more flexible, though not as fast
for xts objects.
