| GHRoutes {ghroute} | R Documentation |
GHRoutes is a class of objects representing results from the
GraphHopper routing when output="gh" is used.
I behaves like a non-mutable list such that usual
operations such as subsetting, element extraction, iteration and
length() work as expected.
However, the object should be consiered non-mutable,
i.e., it is not possible to assign new values into an existing
object. Although subsetting is allowed, concatenation is not.
The object itself contains Java references which enables low-level access to the underlying results using tha GraphHopper Java API.
It is the only result type which supports representation of
alternative routes. If alt=TRUE is used then each (virtual)
element contains a list of result paths of which the first one is
considerend the best according to GraphHopper.
Note that this API is considered experimental and is subject to change.
