extract element, row, etc from general array structure
...difying it to suit my own ends. wapply() takes a vector,
and repeatedly applies a function FUNC (decided at run-time) to
windows of the data. The modification I've made is to generalize
the return structures - if a scalar is returned by FUNC, wapply
returns a vector. If FUNC gives a vector, wappaly returns a
matrix. etc...
A complementary function I'm trying to build is one that extracts
the results of FUNC for window N. As I see it, the logic would
be something like this:
if:
foo<-wapply(some.time.series, some.vector.returning.function)
foo is a matrix. The "extract"...
