FailuRe 2

So I am trying to do a new type of test in R... it's really quite simple, theoretically, but part of the test means that I need part of my data to be assigned as a "blocking factor" while other parts are random effects.  Right, R should totally be able to do this, and I am sure it can... but try searching this baby on Google:

Which of the above actually pertains to R statistical software, eh? I have spent enough of my life learning about the R factor in insulation (thank you Energy Economics class)... give me some STATS!! <3
