Week 16: Random sampling

See the bottom of this page for this weeks Challenges. The index page for the sampling lesson is somewhat incomplete.


This week's videos and exercises are brand spankin' newly created by me! Lots of mistakes to find.

  • Reading and challenge. This has a bit of motivational text. Do the "Is it available?" challenge in the data archiving section.

Loading spatial data

This lesson uses some spatial datasets so this page describes how to get them into R.

Random sampling in space
