Assignment 1

Background

This is the repository for the 'Collaborative Social Science Data Analysis' course taught by @christophergandrud at the Hertie School of Governance.

Style guide: We use Hadley Wickham´s Style Guide from r-pkgs.had.co.nz/style.html.

In our first assignment we use the core R data sets 'Orange' and 'Loblolly' and explore the growth of Orange and Loblolly trees over time.

Loading data sets 'Orange' and 'Loblolly'

As indicated by the prefix 1_orange.R, 'Orange' is the primary data file and should be run first. By copying the commands into R, R will automatically run the commands set in the 2_loblolly.R file, as the first file is dynamically linked to the second.

Data exploration

In the Orange data set we first explored the data set and its specifications. Then we ran summary descriptive statistics to explore the growth of Orange trees over time. We also created a function in R to find out the mean circumference of the Orange trees in the sample.

In the Lobolly data set we explored the data set and its specifications before we ran summary descriptive statistics to explore the growth of Loblolly trees over time.

Note: We pair programmed this assignment together, so while pushes have been down on one computer, work was done collectively.
