Dear Michael,

Many thanks for writing.

> Do any of the suggestions in section 1.5.3 of Writing R Extensions "Load hooks" work?

I thought I had tried all the various permutations in .onLoad but at your prompting I tried some more and this seems to work:

.onLoad <- function (libname, pkgname) {
  # set up default landmarks object
         envir = parent.env(environment()),


It doesn't seem to tickle R CMD check, but I'm not yet convinced that it is 100% safe. Any comments either way are welcome!

Best wishes,
