sfNetwork-class

This class uses a combination of a sf layer and an igraph
object to represent transport networks that can be used for routing and
other network analyses.

Tools for transport planning with an emphasis on spatial transport
data and non-motorized modes. Enables common transport planning tasks including:
downloading and cleaning transport datasets; creating geographic "desire lines"
from origin-destination (OD) data; route assignment, locally and via
interfaces to routing services such as <https://cyclestreets.net/> and
calculation of route segment attributes such as bearing.
The package implements the 'travel flow aggregration' method
described in Morgan and Lovelace (2020) <doi:10.1177/2399808320942779>.
Further information on the package's aim and scope can be found
in the vignettes and in a paper in the R Journal
(Lovelace and Ellison 2018) <doi:10.32614/RJ-2018-053>.
This package Suggests the 'pct' package which at the time of writing
is unavailable on CRAN. You can install it from the repository
'itsleeds/pct' on GitHub.
