If an environment x contains a locked binding y which is also an environment, and then you try to assign a value to a binding inside of y, it can either succeed or fail, depending on how you refer to environment y.
x <- new.env() x$y <- new.env() lockEnvironment(x, bindings = TRUE) # This assignment fails x$y$z <- 1 # Error in x$y$z <- 1 : cannot change value of locked binding for 'y' # Saving x$y to another variable, and then assigning there works y2 <- x$y y2$z <- 10 # OK print(x$y$z) # 10 Is this a bug or a feature? I realize that x$y is a locked binding while y2 is not. -Winston ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
