However, if we try this with 499+ items we get no answer:
a <- eval(parse(text = paste(rep(1, 499), collapse = "+"))) a
Error: Object "a" not found
And if this eval is passed to any other function, that function exits without error and without returning and object.
Suggest you downgrade to R 1.8.1, which returns an error message:
> eval(parse(text = paste(rep(1, 498), collapse = "+"))) [1] 498
> a=eval(parse(text = paste(rep(1, 499), collapse = "+")))
Error in eval(expr, envir, enclos) : evaluation is nested too deeply: infinite recursion?
I dont have an R 1.9.x handy at the moment.
