Ideally they should all work. What is happening is that the current
implementation of complex assignment wants to use a temporary variable
named *tmp*, which it can't when the evaluation environment is locked.
Assignments in compiled code use a different mechanism that I hope
will eventually be po
Shouldn't the following 4 ways to alter an object in a locked environment
either all work or all fail? (All working would be nice, I think.)
E <- new.env()
assign("var", c(1,2,3,4), envir=E)
lockEnvironment(E, bindings=FALSE)
E$var[1] <- 101 ; E$var
#[1] 101 2 3
local(var[2]
