Hi R-devel,
The following code:
all.equal(baseenv(), baseenv())
gives the error when run in a clean R session with latest R-devel (r66650):
kevin:~$ R --vanilla --slave -e "all.equal(baseenv(), baseenv())"
Error in all.equal.envRefClass(target[[i]], current[[i]],
check.attributes = check.attributes, :
attempt to apply non-function
Calls: all.equal ... all.equal.list -> all.equal -> all.equal.envRefClass
Execution halted
Although I don't know if it's helpful -- it appears that packages that
include some S4 machinery will effect the outcome of this error, e.g.
if we load 'Biobase' first:
kevin:~$ R --vanilla --slave -e
"suppressPackageStartupMessages(library(Biobase));
all.equal(baseenv(), baseenv())"
Error in target$getClass() : object '.refClassDef' not found
Calls: all.equal ... all.equal.list -> all.equal ->
all.equal.envRefClass -> <Anonymous>
Execution halted
We were bumping into an error with this in Rcpp -- we used all.equal
(through RUnit) to confirm that baseenv(), and a function returning
the base environment, would return TRUE.
For completeness:
kevin:~$ R --vanilla --slave -e "sessionInfo()"
