Review Body


Did you manage to reproduce it?
Partially Reproducible
Reproducibility rating
How much of the paper did you manage to reproduce?
2 / 10
Briefly describe the procedure followed/tools used to reproduce it

We downloaded the zipped github, Opened it in R, and Run the script. It ran perfectly in 2 different machines, however, the only figure that matched a figure from the paper was figure 1, and there were slight differences in the cluster generated and the location of some cities.

Briefly describe your familiarity with the procedure/tools used by the paper.

We are familiar with R, but not with the details of the scientific research done.

Which type of operating system were you working in?
Windows Operating System
What additional software did you need to install?

We needed to install the "factoextra" package.

What software did you use

R and R Studio.

What were the main challenges you ran into (if any)?


What were the positive features of this approach?

The script ran without any changes on 2 different machines.

Any other comments/suggestions on the reproducibility approach?

It would be nice to link to the software from the paper; if we only had the paper, we would not know that the script existed.
