%description
An interface for performing climate matching using the Euclidean
"Climatch" algorithm. Functions provide a vector of climatch scores (0-10)
for each location (i.e., grid cell) within the recipient region, the
percent of climatch scores >= a threshold value, and mean climatch score.
Tools for parallelization and visualizations are also provided. Note that
the floor function that rounds the climatch score down to the nearest
integer has been removed in this implementation and the “Climatch”
algorithm, also referred to as the “Climate” algorithm, is described in:
Crombie, J., Brown, L., Lizzio, J., & Hood, G. (2008). “Climatch user
manual”. The method for the percent score is described in: Howeth, J.G.,
Gantz, C.A., Angermeier, P.L., Frimpong, E.A., Hoff, M.H., Keller, R.P.,
Mandrak, N.E., Marchetti, M.P., Olden, J.D., Romagosa, C.M., and Lodge,
D.M. (2016). <doi:10.1111/ddi.12391>.
