Hi, Calling
gdistance::shortestPath gives me the error Error in asMethod(object) : not a symmetric matrix; consider forceSymmetric() or symmpart() The output of dput(.traceback()) is pairlist("stop(\"not a symmetric matrix; consider forceSymmetric() or symmpart()\")", "asMethod(object)", "as(Laplacian,\"symmetricMatrix\")", ".Laplacian(x)", ".flowMap(x, ci, cj, tc)", ".local(x, origin, goal, ...)", c("passage(conduct_Tobler, origin =sites@coords[5, ], goal = sites@coords[3, ", " ])"), c("passage(conduct_Tobler, origin = sites@coords[5, ], goal = sites@coords[3, ", " ])"), "eval(ei, envir)", "eval(ei, envir)", "withVisible(eval(ei, envir))", "source(\"./Skript.R\")") Is that enough for anyone to point me in the right direction? I am aware that this question would be probably better posted on r-sig-geo, but as I am just an HPC janitor trying to help a customer and am not a geo-scientist myself, I thought I'd ask here first before signing up to (yet another) list.
