Should get you started

We expect you to first make an effort to learn about and write your
own code, rather than asking us to write it for you.

The dataset is very unbalanced, meaning that some individuals have few observations and others have many. Because I plan on running Generalized Linear Models for panel data using pglm and the package has file size restrictions, I want to create 4 randomly selected subsets of 2500 individuals from the main dataset. What functions and code would I use to do this?
