package

问题 I am trying to unload a package with all of its dependencies. The problem that I am running into is the order in which to unload dependencies. Because dependencies are recursive, they can only be unloaded from bottom-up in the dependency tree. Is there an easy or native way in R to accomplish this? Below a first go in what I would like to accomplish: eval_current <- function(expr, envir=parent.frame(), timeout=60){ #set the timeout setTimeLimit(elapsed=timeout, transient=TRUE); #currently

问题 I have built a package for shiny that allows the user to interact with reactive objects in their global environment. I think it's a game changer for troubleshooting. However, I know that CRAN will reject this due to the manipulation of the global environment. I see answers directing users to create a new environment but I don't see how to access the objects of that environment in the environment pane, I just see the environment name. If I run something like this from this example: Global
