Coursera - Getting and Cleaning Data - Week 1 - Downloading Files

Get/set your working directory in R using getwd() and setwd().

Check for and create directories using file.exists("directoryName") and dir.create("directoryName")

Getting data from the internet using download.file(url="", destfile="", method="curl")

• If the URL starts with http, you can use download.file()
• If the URL starts with https, you may need to set method="curl" on a Mac - Windows is ok with the default method
• Be sure to record when you downloaded the file.
