pol345.student allows students to unpack and complete questions in the pre-precept handouts for Princeton University’s course Politics 345 (as run by Marc Ratkovic and Will Lowe in Fall 2019).
Installation
The problem sets are a bit too big for CRAN, so you’ll want to make sure you’ve got the devtools package installed. Then grab the package from GitHub like this:
Updating
The package can be updated while installed by calling
For good measure, now restart your R session. In RStudio use the menu: Session > Restart R.
Usage
Working on a handout
To start work on handout one, type
get_handout(1)This will unpack the handout materials into a folder called handout1 in your current working directory. (Type getwd() if you’re not sure where that is. You can change it using setwd or through RStudio’s Session menu).
If you want to fresh start on the same handout, you’ll can unpack again under a different name (the get_handout function won’t overwrite an existing folder.) To do this add a newname argument when y ou call the function. So, if you want your new copy to be called “handout1-for-real”, then use
get_handout(1, newname = "handout1-for-real")Provided there’s not already a folder of that name in your current working directory, you’ll get a fresh set of handout materials unpacked there.
If you want to preview the questions in a handout materials without unpacking it into your local file system, use
preview_handout(1)Working on a precept
Working on precept is just the same; just use get_precept(1), get_precept(1, newname = "precept1-second-go"), or preview_precept(1) as above.
Sneak preview
You can view precept 1’s ‘answers’ with
get_precept_answers(1)Note: this shows one way to answer the questions. Often there will be others, so do not automatically assume that your code is incorrect if it does not match the code in the answers.
