Limit required packages

[adamSales]

Any package that our scripts use that doesn't ship with the default R installation will have to be installed, which will take time and can cause hangups. So let's try to limit the packages called by our scripts.

In particular, scripts/02-effect-est.Rmd calls dplyr, tidyr, and kableExtra. I think that tidyr and kableExtra are unnecessary. A little rewriting of lines 44-46 will make dplyr unnecessary

I will keep this in mind while I write -- what I plan to do is add code that will automatically install packages if the user doesn't have them already. So it will only add a little bit of extra run time.

My current solution is to include the code that will automatically load packages and there are also fully compiled markdowns of each script in this folder, which could be viewed on Github directly. Therefore, if someone can't get the early scripts to run, they can walk through them still.

Good idea.
Building off your work, I just committed d2ee4cb with scripts/installPackages.r

which participants can run at the very beginning, so everything is installing while we're talking. I think we should leave all of the code you wrote, cuz people might come in late or whatever.

Okay, perfect!
