 Hi, this is Dr. Don. I'm going to take a couple of minutes and show you how to update packages. Remember the packages are an open source project and have a lot of individuals that are taking care of those packages and occasionally they will publish an update. Plastic Cloud doesn't automatically scan and look for everything that's updated. You have to manually update packages and I want to show you how to do that. This is the files window, the files pane I guess, the window pane down at the bottom. What you can do is click on packages and then click on update. And what it does, it goes through and it looks at the packages you have installed and it will tell you in this column the version that you have installed and in this column it will tell you the latest version that's available. You can see for most of these, these are, I don't use very much, it looks like there's a new version available. One package I'm interested in is called Infer and I'm going to look at it and you can see there I've got to install the version 1.0 but there's a new version 1.06. So I want to update that and what I'm going to do is just to click on that. First thing I'm going to do is select none to make sure I don't have any other packages. Theoretically you can select all and have every package updated but that may take you quite a while. So I like to do them one at a time and again I select none to make sure there's only the one I want. I'm going to select infer and then I'm going to install the update and it will ask you occasionally do you know that you need to restart R and down at the bottom do you want to restart? I usually restart once when I am updating packages and then I ignore the other do you want to restart messages unless I just have to force you. So I'm going to say yes, let's restart once. You can see it's restarting. And now down here you can see it's loading and it went through some comments, steps in the console window. We got back to our normal cursor and it's flashing so it's ready to go. Let's go back here and look at infer back in the packages. I'm going to scroll down and let's see where is it. There's infer and you can see now we've got version six. I want to show you one more that I know I need to update. I'm going to click update again and it's called tidyverse. That is a package we use a lot in this course and it has a lot of sub packages. I usually update it once you know every so often and it takes you know three or four minutes sometimes for tidyverse to update you've got to do some steps. So I'm going to say install updates, do you want to restart? I'm going to say yes one time, let it restart. Now I'm going to ignore the second time and just let it keep working. And you see a lot of red over here where it's doing things in the console. As I said there's a lot of sub packages in the tidyverse packages so this takes a while and I'm just going to pause it and let it run it may take a full minute or more. Okay it took about 30 seconds and you can see now we've got back to our start cursor. So I'm going to go over here back in the packages and scroll down and look in tidyverse and make sure it has been updated. Tidyverse one more. There's tidyverse we're the latest version 2.0. So that's all there is to it. I hope this helps. Thank you. Thank you. Bye. Bye. Bye.
