 Hi, everyone, this is going to be another fairly short video. I'm just going to do something that I've actually shown you how to do one time before, but I'm going to show you again. I want to take this demonstration data project that I'm going to use to show you how to do problem set for and also your semester-long project. Remember, do not use this data file yourself, because the whole point, you can use any of these others. But the whole point is for you to be using something original, at least not directly copying my work. You've got to be doing something a little bit different. But I want to move it over to that demonstration project directory. So I'm going to do what I did in the last video. I'm going to do copy 2. And I've got to come out a couple of levels. And I'm going to this demonstration semester project. And normally, I would put it in a data directory, but this is the only data I'm going to use all semester. So I'm going to make things a little easier on you. It's not the best way for organizing, but it's going to make things simpler through the semester. So I'm just going to save it in the main directory. The next thing I want to do is actually get over to that project and start using it. So there are a couple of ways I can do that. I can come to the recent projects, and it's there. If you don't actually have it in your recent projects, it won't be there. Another way is I can come over here, and this also has the recent projects, and it's there. Or I can come to the File menu, and I can say Open Project. This is the hard way. And I have to know, in order to do it this way, I have to know where it is on my computer. And I know that I have in my documents, I've set up this R projects directory. That's a slight change from earlier in the semester because I got a new computer. So I just named it R projects. And down there in R projects is the demonstration semester project. And to open it, I have to look for the file that has the .rproj extension, .rproj. As the end of the file name, I can double click on it, or I can highlight it and click Open. Either way, that's going to open up that project. And when we get there, I copied that data set, the demonstration data.csv. And there it is. I'm going to leave that for now. And on the next video, which is going to be a little longer, I'm actually going to open up that data set and do the first several problems on problem set four.
