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)
I could not get those to run with method="libcurl", possibly since I have not yet updated to 3.2.2? This did run:
checkfun <- function(ver) {
uu <- paste0(urlhead,ver, urltail)
rr <- readLines(url(uu))
any(grepl("could not find function.*REMLcrit",rr))
}
sapply(versions,checkfun)
devel-osx-x86_64-clang release-osx-x86_64-mavericks
FALSE FALSE
release-osx-x86_64-snowleopard
TRUE
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 Possibly the Snow Leopard test build on CRAN is using an out-of-date version of lme4 ... ?

That is the latest version at CRAN for SL: http://cran.cnr.berkeley.edu/bin/macosx/contrib/3.2/ Is that version "out of date"? I suppose it might be, since I see this at the top of the CRAN package check: ? using R version 3.2.0 Patched (2015-04-28 r68272) ? using platform: x86_64-apple-darwin10.8.0 (64-bit) ? using session charset: UTF-8 ? checking for file ?gamm4/DESCRIPTION? ... OK ? this is package ?gamm4? version ?0.2-3? I get this at the console:
