In this video we continue through Examples 4-6 in Mod9Script.R and learn how to read in comma-delimited and column-aligned plain text data files using the read.csv() and read.fwf() functions.
You may be able to learn how to use these functions on your own from the course notes, by reading through Mod9Script.R and from the functions' help pages. But watching this video will probably speed up the process, so I strongly encourage you to watch it.
