Week 16: Random sampling
See the bottom of this page for this weeks Challenges. The index page for the sampling lesson is somewhat incomplete.
Preparation
This week's videos and exercises are brand spankin' newly created by me! Lots of mistakes to find.
The data life cycle
- 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.
- Video for Mac users demonstrating how to get the data downloaded in the correct directory structure. Your mac is a bit too helpful without some adjustments.
- Instructions for loading spatial data
