In rstudio/reticulate: Interface to 'Python'

Traverse a Python iterator or generator

Description

Traverse a Python iterator or generator

Usage

as_iterator(x)

iterate(it, f = base::identity, simplify = TRUE)

iter_next(it, completed = NULL)

Arguments

x	Python iterator or iterable
it	Python iterator or generator
f	Function to apply to each item. By default applies the identity function which just reflects back the value of the item.
simplify	Should the result be simplified to a vector if possible?
completed	Sentinel value to return from iter_next() if the iteration completes (defaults to NULL but can be any R value you specify).

Details

Simplification is only attempted all elements are length 1 vectors of type "character", "complex", "double", "integer", or "logical".

Value

For iterate(), A list or vector containing the results of calling f on each item in x (invisibly); For iter_next(), the next value in the iteration (or the sentinel completed value if the iteration is complete).
