R avoiding “restarting interrupted promise evaluation” warning

Question

Problem

You can also try this without silent=TRUE if you want each error message to show. In neither case will you get the message about promises:

foo <- function() stop("Foo error")
bar <- function(x) {
    try(eval.parent(substitute(x)), silent = TRUE)
    x
}
bar(foo())
