1. Using the gapminder data, create a plot comparing log(gdp PerCa with Life Exp and show three different smoothers in three different colors with a legend showing each smoother type. 2. In a paragraph compare and contrast the smoother types. LOESS, Cubic Spline, and OLS 3. Look at the gapminder data with str() 4. Create a linear model of the gapminder data with life expectancy as the target of a multifactor model built from gdpPercap, pop, and continent. Store it in a variable called ...

Describe the difference between a paper map and a GIS map Answer GIS maps are dynamic You can manipulate the features of a GIS map, you cannot change the features of a paper map This includes zoom, selecting features you wish to see, and access a database for more features How is a GIS map organized? Answer A GIS map consists of 1 or more dataframes A data frame is a collection of layers A layer is a collection of features A feature represents a real-world object What is a feature? 3 ...
