However, there are times when you're going to want to do that and for that purpose, R provides you with four different ways to edit R objects. Let's look at these. The first is called edit and here in line 12, I've setup a line that will allow me to edit the values in ChickWeight. The changes that I make are going to be saved into a vector called Chickens. So let's make an obvious change here. I'm going to change the time to 345 something, and when I quit, you'll see that the object Chicken has been created. So let's go over and look at that object, and if I type in Chickens and hit Return and then scroll up to the top, you'll see that my time is now part of Chickens. If I want to, I can create a list and edit that. So if I use edit as.list(ChickWeight), as I've shown in line 14, what I get is…
