plot(data$stations, data$revenue, xlab="stations", ylab="revenue", col = findInterval(x$year, c(2005, 2010, 2015)) Please note that If you have many (20-30) intervals, colour handling will be more complex. But I assume you have maximum 5-10 intervals. So, the piece of code above will work for you. > 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 > > > Am 30.05.2017 um 18:26 schrieb Ismail SEZEN: >>> On 30 May 2017, at 19:02, Tobias Christoph <s3toc...@uni-bayreuth.de> >>> <mailto:s3toc...@uni-bayreuth.de> wrote: >>> >>> Hey Guys, >>> >>> I just try to differentiate certain values in my plot by colour or symbol. >>> >>> I have panel data with three dimensions (number of stations, revenue, >>> years).
