Greetings- I've noticed that lme4 isn't available for Mac under R 3. Looks like its throwing errors at compile time, according to the logs.
More precisely, if fails checks: checking tests ... ERROR Running the tests in 'tests/simulate.R' failed. Last 13 lines of output:
s4 <- simulate(gm1,10) stopifnot(is.list(s4), sapply(s4,ncol)==2,

r1 <- pboot(gm0,gm1, 10)
Error in logLik(refit(m1, s)) : error in evaluating the argument 'object' in selecting a method for function 'logLik': Error in mer_finalize(object) : Downdated X'X is not positive definite, 1. Calls: refit -> refit -> mer_finalize -> .Call Calls: pboot -> apply -> FUN -> logLik Execution halted that's why it's not available. I tried two different compilers just to make sure it's not a compiler issue and it throws the same error, so I fear this is over to the maintainers. Cheers, Simon
It looks like Ben is aware of the issue and fixing it: https://stat.ethz.ch/pipermail/r-sig-mixed-models/2013q2/020170.html Cheers, Michael
