Project #4 posted

In case you want to get an early start on Project #4, I’ve posted it to the lecture detail page for April 2nd. After you’ve installed strataG in R, you may encounter an error that prevents the library from loading. I had that problem with v3.5.3 on an iMac, but v3.5.1 works fine on my MacBook. I’ll try to sort out the problem before tomorrow, but if I can’t, Kristen and I will develop a workaround.
