Graphing in R

Frank McCown outlines a quick and simple intro exercise for graphing in R:

A few notes to keep in mind as you run through the exercise:

• If you need a refresher on creating tab delimited files, ehow has you covered:

• If you save your tabbed file with .tab per the ehow instructions, make sure to edit Frank's code:
autos_data <- read.table("C:/R/autos.dat", header=T, sep="\t")
#becomes
autos_data <- read.table("C:/R/autos.tab", header=T, sep="\t"
• Make sure you're using forward slashes when you set the file path! This post discusses that pesky character string error.
