Dear R-Gurus,
is it possible to evaluate foreign R code in such a safe way, that it has
no chance to confuse the global environment?
The follwing does not suffice, because the untrusted code might e.g.
contain a superassignment ("<<-"):
connection <- textConnection(some.untrusted.code)
try(eval(parse(connection), envir=new.env()))
close(connection)
