\section{A Linear Regression}

Here, we generate some sample data. By default, sweave echoes the results - showing
us what commands are run in R. But we can stop that in our code chunk by specifying
 "echo=FALSE". In the example below, we will generate random variables from the
 normal and uniform distribution, put them in a data frame, run a linear regression
 and output a table that shows us the pertinent information from the regression.  

% R Code Chunk

library(xtable)
set.seed(1234) # Set seed for RNG
