Dear R-Team, there seems to be a minor bug in the example for optim(). In the travelling salseman part of the example section the lines text(x, y, names(eurodist), cex=3D0.8) (7th line from bottom) text(x, y, names(eurodist), cex=3D0.8) (last line) do not produce any oputput, because names(eurodist) has value "NULL". To get the intended output one has just to substitute names() by labels(). So the correct line will be: text(x, y, labels(eurodist), cex=3D0.8) . Thanks for all your effort and the software you created.
