[Previously saved workspace restored] > example(loess) loess> cars.lo <- loess(dist ~ speed, cars) Error: object "R_loess_raw" not found I saw this first with a self-built 2.3.1 version, that worked fine under 10.3 . Hoping that a Tiger build would solve matters, I installed the fresh 2.4.0 from the downloaded disk image. As you can see, the error message persists. Curiously, the ppc/stats.so file somewhere deep i...

Well... this may be a red herring after all, but it's an interesting one! It turns out I have got DYLD_LIBRARY_PATH set. This gets exported to R (or rather, affects the loader that loads the R process?), and somehow mixes up the way symbols are exported. Something that applies to launching R from the command line (/usr/bin/R) AND via LaunchServices (open -a R). Once I noticed that invoking

I noticed that in https://svn.r-project.org/R/trunk/src/library/stats/R/loess.R that we are now calling R_loess_raw, R_lowesw, R_lowesp, etc. I'm interested to know what is the benefit/reason for the 'R_', as I am unfamiliar with this prefix and do not see it mentioned in 'Writing R Extensions.' Thanks, Ben

...RAN and couldn't find any information related to possible crash causes. I've used the ATLAS BLAS for about 6 months on this machine (it's a new machine) with R 2.6.2. Using debug(stats:::simpleLoess), I've found that the crash occurs on the first iteration of the line: z <- .C(R_loess_raw, as.double(y), as.double(x), as.double(weights), as.double(robust), as.integer(D), as.integer(N), as.double(span), as.integer(degree), as.integer(nonparametric), as.integer(order.drop.sqr), as.integer(sum.drop.sqr), as.double(span...

I have tried poking around in the R source code for the R_loess_raw (loessc.c) method, but I find it quite dense and hard to follow... if anyone has some debugging ideas, they would be greatly appreciated.
