You might want to have a look at the reshape package, http://had.co.nz/reshape, which provides a more general and flexible framework for reshaping data in R. The version of warpbreaks I have doesn't have the replicate variable, so unfortunately I can't provide you with example code for this case. However, you should be able to figure it out for your data using the documentation available on the website.
