[R] incomplete latin square design

[Lei Liu]

Hi there,

I have a question on cross over design. There are 3 treatments, each 
with 3 dose levels, a total of 27 treatment combinations. Each 
treatment combination is given to a subject in 1 day. However, we can 
only keep each subject for 9 days, i.e. each subject can have only 
take 9 treatment combinations. This looks like a incomplete latin 
square design. Is there any function in R to create such design? Thanks a lot!
