Drawing Latin Squares with agricolae

We return, once again, to the agricolae package to examine what a Latin Square design can look like. Here's an example:

     [,1] [,2] [,3] [,4]
[1,] "B"  "D"  "A"  "C" 
[2,] "A"  "C"  "D"  "B" 
[3,] "D"  "B"  "C"  "A" 
[4,] "C"  "A"  "B"  "D"

Since a Latin Square experiment has two blocking factors, you can see that in this design, each treatment appears once in both each row (blocking factor 1) and each column (blocking factor 2).

Look at the help page for design.lsd() by typing ?design.lsd in the console for any help you need designing your Latin Square experiment.
