<div dir="ltr"><div><div><div><div><div>Hi folks.<br><br></div>I just taught an IRT workshop on Sunday using ltm via RKWard, and I had a lot of people claim that they couldn't get ltm and the dependencies to download. This was a familiar problem from when I taught a semester-long basic stats class with RKWard. This time, though, I was able to sit down with the people and figure out what was going wrong.<br>
<br></div>It seems that after you pick a CRAN mirror, and RKWard/R finds the necessary package, if you click "OK" instead of "Apply," it still closes out the window, but doesn't download the package. The analysis you're trying to do fails, of course, and you can't figure out why. You click "Run Again," but it all happens again.<br>
<br>I had to sit down with at least 5 people, go to the package management screen, search for ltm, then hit "Apply" and <i>then</i> "OK." In all cases, everything worked great then.<br><br></div>Now, after many years of using Windows, I know that if there's an "Apply" button, you'd better press it before "OK", but this was especially confusing for the Mac users, especially since the "Apply" button is way over on the left edge of the window, contrary to the UI conventions on the Mac, which put the most likely, default button on the right, where it's easy (for right-handed people) to get to.<br>
<br></div>There was at least one Windows user who was having the same problem.<br><br></div>Can't the "OK" button apply the change and then close?<br></div>
