Not possible I think, but I could write a custom glpk package, that exposes callbacks...
I think you should change "ressource" to "resource".
(in RStudio if I am not mistaken you can run a spell checker on Rmd)

There seems to be something not quite right with the TSP formulation. The path seems to disappear and reappear, based on the example shown:
kable(head(arrange(paths, trip_id), 12))
| trip_id | property | idx_val | x | y |
|---|---|---|---|---|
| 1 | from | 7 | 267.42898 | 439.3217 |
| 1 | to | 1 | 398.89216 | 398.9946 |
| 2 | from | 1 | 398.89216 | 398.9946 |
| 2 | to | 2 | 376.78255 | 296.8970 |
| 3 | from | 5 | 180.64706 | 496.9183 |
| 3 | to | 3 | 195.62784 | 452.6550 |
| 4 | from | 6 | 99.17237 | 447.9782 |
| 4 | to | 4 | 170.77835 | 440.4243 |
| 5 | from | 4 | 170.77835 | 440.4243 |
| 5 | to | 5 | 180.64706 | 496.9183 |
| 6 | from | 10 | 83.78474 | 388.6032 |
| 6 | to | 6 | 99.17237 | 447.9782 |
trip_id 2 ends in point 2, but trip_id 3 starts at point 5
thanks.
