The get() function might be one of the most useful utilities in R. However I’ve never use this function before I write this page. Shame on me.
Well, let’s get to the point. The job of the get() function is actually quite simple: given the name of an object, it fetches the object itself. See the example below:
> x <- c(1:3) > x  1 2 3 > get("x")  1 2 3
It’s easy to imagine how useful this function is.
