Subject: [R] list of all objects - just being curious
Hello all,
to obtain a list of all objects in all search paths, I've found the
following to work:
biglist <- sapply(1:length(search()), objects)
This more obvious one, however, does not work:
biglist <- sapply(search(), objects)
Error in pos.to.env(pos) : invalid argument
Still, search() gives
[1] ".GlobalEnv" "package:ctest" "Autoloads" "package:base"
and objects(".GlobalEnv"), objects("package:ctest") etc. all
give their
respective vectors. So why does the sapply() construction not
work here?
I've also tried a for() loop ("for (I in search())
print(objects(I))") with
the same error message. Again, "for (I in 1:length(search()))
print(objects(I))" works all right.
What am I misunderstanding?
