Details

A quick way to break up a large xts object by standard time periods; e.g. 'months', 'quarters', 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.

Examples

data(sample_matrix)
x <- as.xts(sample_matrix)


split(x)
split(x, f="weeks")
split(x, f="weeks", k=4)
