11. Who is creating these packages?
R is the work of dozens upon dozens of people; primarily University Professors and PhD Students; though also individuals on their spare time; and more recently companies.
They have written many packages to make it easier for everyone to analyze data.

12. Most From Universities
Many University Researchers receive FEDERAL and other grants to work on projects. For some projects, part of that money goes to create R libraries.
