As pointed out in this lme4 issue: https://github.com/lme4/lme4/issues/302 , lme4 is behaving badly on Snow Leopard, failing to find an (apparently) exported function
urlhead <- "https://www.r-project.org/nosvn/R.check/r-"; urltail <- "/gamm4-00check.html" versions <- c("devel-osx-x86_64-clang", "release-osx-x86_64-mavericks", "release-osx-x86_64-snowleopard") checkfun <- function(ver) { uu <- paste0(urlhead,ver,urltail) rr <- readLines(url(uu,method="libcurl")) any(grepl("could not find function.*REMLcrit",rr)) } sapply(versions,checkfun) Here's the (broken to make Gmane happy) link to the bad case: https://www.r-project.org/nosvn/R.check/ r-release-osx-x86_64-snowleopard/gamm4-00check.html The REMLcrit function is exported, at least in all recent versions of the package (and we haven't been able to reproduce on any other platforms). Any ideas ... ? Possibly the Snow Leopard test build on CRAN is using an out-of-date version of lme4 ... ? thanks Ben Bolker _______________________________________________ R-SIG-Mac mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-mac
