 Hi folks, this is Dr. D. I wanted to go over with you an issue that's now occurring when we're using Posit Cloud in our Lab 2 Rehears 1. This is down here where we're trying to get the summary of the data, the New York City Films data, and we're using this summary tools to explore. Now this tool is CC4 again, is a great view. We use the library summary tools, we load that into the, excuse me, the package summary tools we loaded in the library, and then we use this view function. The summary tools will let us use a DF summary function and we put in there the name of the data object, and it does produce a very useful data object. I'll show you here. I'm going to run this code, and it's kind of hard to see because I'm out of room here, but over here in the files menu, I'm just going to move this a little bit so you can see a little bit more, the viewer opens up and we've got this data summary that tells us how many rows, how many variables, and it starts giving you a lot of information over here on the far right. We actually got little small graphs about each of these particular variables. That's a very useful tool. Problem is now in poset cloud, if we try to knit this document, let's just say we're through and we've put on down and we filled in the rest of the code chunks, and we knit it, I'm going to click on knit, knit to PDF, takes a few minutes here, a few seconds really. While this is happening, the PDF opened up over here, okay, you can see the edge of that. I'm just going to close that, and it's created and it's stored in your workspace, but you're given this screen here. It opens up a new tab, says, pop, poset workbench, the requested page was not found, click here to go back. I find it's easier just to close that new tab that it opened up and go back here to poset cloud. After you've looked at the data frame summary down there, what I want you to do is we're going to comment out this last line of code here. Just a single pound symbol, hashtag, if you want to call it that, and that makes this now just a comment, you can see it turn green, and R won't try to run it when we knit. Now if I knit to PDF, again you can't see the whole PDF and you see the black edge here. Trust me, the PDF opens up just normally and it's over here in your files menu. Everything works hunky dory. So remember that, after you've viewed it and before you knit, comment out that view function so you won't have that crazy poset workbench pop up. Hope this helps.
