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()\")",
".Laplacian(x)", ".flowMap(x, ci, cj, tc)",
".local(x, origin, goal, ...)",
c("passage(conduct_Tobler, origin =sites at coords[5, ], goal = sites at coords[3, ", " ])"),
c("passage(conduct_Tobler, origin = sites at coords[5, ], goal = sites at coords[3, ", " ])"),
"eval(ei, envir)", "eval(ei, envir)",
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.
