BoxesFD
Description
Calculation of the fractal dimension of a coastline using the boxes methods
Usage
BoxesFD(BinputPath, netPath, outputPath, year, r, pearsonValue, writeF, showF)
Arguments
BinputPath |
All origin coastline files path |
netPath |
All fishnet files path |
outputPath |
All results will be exported here |
year |
R vector object, which represent your study time |
r |
R vector object, which represent your study scale |
pearsonValue |
The Pearson coefficient of your input data |
writeF |
Exporting Function's result |
showF |
Drawing Function's result |
Value
An .xlsx file containing the results of the coastline fractal dimension
Examples
BinputPath = list.files(system.file('extdata', package = 'CoastlineFD'),full.names = TRUE)[1]
