Have you ever experience a situation where you want to import and combine hundred of datasets? If you do this manually, then it will take too much time. On the other hand, we can use a simple R programming to solve this problem in easily and quickly. Therefore, I would like to share two methods of combining all small files in a directory into a single dataset…

Today I've just faced one challenge...

I work on one project, and we need to decide which assets from this company will be visited initially.

As every project, we have limited budget, so we should find some variables to indicate a priority scale.

After some discussion, someone said: let's find the assets close to schools and hospitals. Those must be inspected firstly than others.

Everybody agreed with the voice, but how would be possible to map every school and…
