In blasee/fetchR: Calculate Wind Fetch

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").
