After a bit more investigating I've narrowed it down. The notes can be
generated by having
d1 = setRefClass("d1", fields=list(x = "numeric"))
d1$accessors("x")
**and** having ByteCompile: true. Commenting out the accessors line removes
the visible binding note. The x=NULL or globalVariables("x") trick
doesn't work.
A stackoverflow answer suggests that I need to add
assign(variable,NULL, envir = .GlobalEnv)
but this generates a new NOTE under R CMD check
I've not been able to find another package that uses accessors and
ByteCompile
Thanks
