Module 3: Data manipulation in R

Learn to bin, transform and add new vectors to datasets in R. You will also install and load packages to build a map using coordinate data.

Video #3

For this video we will be working with the USpop.csv dataset again.

IF you are well practiced with reading data into R, feel free to read in our existing data object.

Make an R Notebook for this walk through tutorial to save all the code you will be learning. We will cover:

• Adding new vectors to datasets
• Numeric versus character values
• for loops in R
• transformations
• binning data
• using maps to plot points on a map
• Splitting datasets into quantiles

Walk-through code

• R Markdown from video (Slideshow)

Data Files

• USPop.csv

Associated code and data files are also within the compressed data file.
