Drawing Graeco-Latin Squares with agricolae
As we've seen, agricolae provides us the ability to draw all of the experimental designs we've used so far, and they can also draw Graeco-Latin squares. One difference in the input to design.graeco() that we haven't seen before is that we'll need to input 2 vectors, trt1 and trt2, which must be of equal length. You can think of trt1 as your actual treatment and trt2 as one of your blocking factors. agricolae has been loaded for you.
