title: How to plot columns of a matrix on a single line graph in R
body: <p>I created a function which reads data from a txt file to create a table, some data manipulation occurs and then the results are put into a matrix. This is a sample of the result:</p>
  
  <pre><code>          Canada     France       Germany      Italy        Japan

  <p>I'm trying to figure out how I can plot this data on a graph. I want to have the years as the x - axis and the inflation rate as the y - axis. So in the end I would like one graph with lines (in different colours) for each country.</p>
  
  <p>Is this possible to do?</p>
  
  <p>Any help appreciated, thank you.</p>
