fetchR 2.1-2

Bug fixes

Fix future warnings from CRAN checks on R-devel (#10)

fetchR 2.1-1

Minor changes

You can now specify up to 1 direction per degree on the compass rose (n_directions = 90).

fetchR 2.1-0

Minor changes

Site names are automatically read from the data associated with the shapefile. The names have to be in a column with a name matching the regular expression; ^[Nn]ames{0,1}$.
Created a shiny application for fetchR.
Use on.exit to close the KML file connection in kml,Fetch method.

fetchR 2.0-0

Major changes

fetchR is now generalised to incorporate SpatialPolyons representing any marine location on Earth (#6). As a result, fetchR 2.0 is no longer limited to calculating wind fetch within New Zealand coastal areas.

Rewrite the entire algorithm for calculating wind fetch.

The rgeos::gBuffer function is used to calculate the end points of the fetch vectors at their maximum distance.
The interactions between the fetch vectors and the coastlines, or any of the polygons, are calculated with the rgeos::gIntersection function as opposed to the slow, iterative algorithm used by the package's predecessors.
Computation times have dramatically decreased.

Minor changes

Create a vignette for the package; vignette("introduction-to-fetchR").
