[R] Differentiate values in a plot by colour or symbol

[Tobias Christoph]

Hi Ismael,

thanks for your quick reply.

I was now able to esmitate two intervals with the "findInterval"-Function.

   x
  [1,] 2005 1
  [2,] 2006 1
  [3,] 2007 1
  [4,] 2008 1
  [5,] 2009 1
  [6,] 2010 1
  [7,] 2011 2
  [8,] 2012 2
  [9,] 2013 2
[10,] 2014 2
[11,] 2015 2
[12,] 2016 2

But I was not able to connect the intervals with the plot-function. I 
used the following formular.

"plot(data$stations, data$revenue, xlab="stations", ylab="revenue", 
col(findInterval())"

How can I proceed and get the plot-funktion running?

Maybe it is not running because the years as single numbers are already 
contained in my data-frame?

Cheers,

Toby
