Hi Eric, I know but I can't understand where is the error. the function shortestpath wants: x="TransitionLayer", origin="Coords", goal="Coords" or x="TransitionLayer", origin="numeric", goal="numeric" or x="TransitionLayer", origin="SpatialPointsDataFrame", goal="SpatialPointsDataFrame" so I followed the example in the rWind package and works, than I changed the coordinates and I have the error Il giorno dom 11 lug 2021 alle ore 11:50 Eric Berger < ericjberger at gmail.com> ha scritto:
This error can result from v with NAs. e.g. to reproduce the error message
v <- as.numeric(NA)
if (is.numeric(v) && any(v < 0)) cat("hello world\n")
