Ahh, okay. I think now I understand what you exactly mean. But the plot is stil not working /differentiate the dots by color. I used the following formula.
"plot(data$stations, data$revenue, xlab="stations", ylab="revenue", col = findInterval(data$year, c(2005, 2010, 2015))" I think the problem is stil related to the term "col = findInterval(data$year, c(2005, 2010, 2015))" and its notation. Just to make sure: "data" is the name of the data-table imported in R. "year" is the lable of the column where the years are listed in the data-table?
