Hi, I'm trying to work with rWind but when try to create a shortestpath (From point a to B with gdistance package) I have this error:
Error in if (is.numeric(v) && any(v < 0)) { : missing value where TRUE/FALSE needed so this is the code: library(rWind) library(raster) library(gdistance) w<-wind.dl(2020, 2, 12, 0,-17,28,45,50) #download all Mediterranea area wind<-wind2raster(w) # create two raster about speed and direction wind Conductance<-flow.dispersion(wind) AtoBo<- shortestPath(Conductance,spagna,libano,output="SpatialLines") #create shortestpath (spagna and libano are two SpatialPointsDataFrame) where I wrong?
