TOUR
From TSP v1.1-4
by Michael Hahsler
Class TOUR -- Solution to a traveling salesperson problem
Class to store the solution of a TSP. Objects of this class are returned by
TSP solvers in this package. Essentially, an object of class TOUR is
a permutation vector containing the order of cities to visit.

Usage
## conctructor
TOUR(x, method=NA, tsp=NULL)
## coercion
as.TOUR(object)
## methods
"print"(x, ...)Arguments
- x
- an integer permutation vector or, for the methods
an object of class
TOUR - object
- data (an integer vector) which can be coerced to
TOUR. - method
- character string; method used to create the tour.
- tsp
-
TSPobject the tour applies to. If available then the tour will include the tour length. Also the labes of the cities will be available in the tour (otherwise the labels ofxare used). - ...
- further arguments are passed on.
Details
Since an object of class TOUR is an integer vector, it can be subsetted
as an ordinary vector or coerced to an integer vector using
as.integer(). It also contains the names of the objects as labels.
Additionally, TOUR has the following attributes:
"method", "tour_length".
For most functions, e.g., tour_length or image, the
TSP/ATSP object used to find the tour is still needed, since the tour
does not contain the distance information.

Examples
TOUR(1:10)
## calculate a tour
data("USCA50")
tour <- solve_TSP(USCA50)
tour
## get permutation vector
as.integer(tour)
## get tour length directly from tour
attr(tour, "tour_length")
## show labels
labels(tour)
