title: How to install multiple packages?
body: <p>How would I got about installing multiple packages in R? </p>
  
  <p>I tried the following code:</p>
  
  <pre><code>install.packages("EIAdata", "gdata", "ggmap", "ggplot2","gridExtra","ISOweek","kobe","lubridate","maps","MASS","memisc","pander","plyr","psych","Quandl","quantmod","reshape2","rgeos","Rgnuplot","RODBC","scales","sp","sqldf","stockPortfolio","stringi","stringr","XLConnect", "xlsReadWrite","zipcode")
  </code></pre>
  
  <p>This code works: </p>
  
  <pre><code>install.packages("ggplot2")
  </code></pre>
  
  <p>Why won't the line with the multiple packages work?</p>
