I have a set of data with 2 columns: time, size. There are 20 sets of data. The data is looking at whether the size of a seed affects the time it takes to germinate. How do I then create a numerical variable called 'order' with values 1 to 20 in order to plot a graph or order against time? -- View this message in context: http://r.789695.n4.nabble.com/Order-function-tp4651022.html
