Usage and Installation

In order to participate in the course and to use the course material, you need to

1. install R: download for free at https://www.r-project.org
2. install the RStudio IDE at RStudio.com
3. We recommend to use our code exclusively via RStudio.
4. install this R package in your computer. To do so, just copy and paste those lines into your RStudio console:

if (!require(devtools)) {install.packages("devtools"); library(devtools)}
install_github(repo = "ScPoEcon/ScPoApps")

Shiny Apps

A key part of this course are a series of interactive applications (or apps) that we developed with the shiny framework. You launch the apps from a running R session on your computer. The app will run in your web browser. You launch an app like this from R:

library(ScPoApps)   # load our library
launchApp('SSR_cone')       # runs the `SSR_cone` app in browser

launchApp()                 # no arg produces an error that shows all available apps
Error: Please run `launchApp()` with a valid app as an argument.
Valid apps are: 'anscombe', 'confidence_intervals', 'corr_continuous', 
'datasaurus', 'reg_constrained', 'reg_dummy', 'reg_dummy_example', 
'reg_full', 'reg_multivariate', 'reg_simple', 'reg_standardized', 
'sampling', 'SSR_cone', 'standard_errors_changeN', 'standard_errors_simple'

Here is a screenshot of the SSR_cone app:

Tutorials

In order to run the accompanying tutorials you would type, for example:

library(ScPoApps)
runTutorial("chapter3")

Contribution Workflow - Developers only!

This section is only for people who want to contribute code to this project.

1. fork this repository
2. clone your fork to your computer: git clone url_of_your_fork
3. Start to work on your things on a new branch: git checkout -b new_branch
4. commit your work to that new branch!
5. Place your new stuff on top of the most recent upstream/master:
   1. add the upstream repo as a remote: git remote add upstream [e-mail]:ScPoEcon/ScPoEconometrics.git
   2. Use the rebase command

   # git add your stuff
   # git commit your stuff
   git fetch upstream   # get stuff from upstream
   git rebase upstream/master  # merge upstream master and put your commits on top of it
   

6. push that branch to your fork: git push origin new_branch
7. create pull request on upstream (from your fork at github.com)
