Welcome to the data_hunters!

---

Our role is to collect and cultivate supplemental data sets for use in the openintro or usdata R packages associated with the OpenIntro textbooks.

*If you have an ORCID please email it to me so that it can be included in your credits.

*Be sure to add data sets that are ready to the appropriate tab on the Google Sheets file that we went over during our initial meeting.

We will follow the process for adding new data outlined below and modified from the openintro package.

If you are a better visual learner, there is a screencast linked at the bottom of this page.

The following steps use the devtools and usethis packages for various steps. We recommend using this process when suggesting new datasets to be added to the package. If the dataset is large (>500MB) or you’d like to add a function, please open an issue first for discussion before making the pull request.

1. Fork and clone the repo with usethis::create_from_github("npaterno/data_hunters", fork = TRUE)
2. Start a new pull request with usethis::pr_init("BRANCH-NAME"), where BRANCH-NAME is an informative branch name.
3. If adding a file that is not an .rda file to begin with (Excel, csv, etc.), create a folder in the data-raw folder with the name of the dataset (how you’d like it to show up in the package). Please use snake_case for naming, e.g. name_of_dataset.
4. Place your dataset in its raw form in the folder.
5. Also in the data-raw folder, create a new R script called name_of_dataset-dataprep.R and write the code needed to read in the file, make any modifications to the data that are needed (if any), and end with usethis::use_data() to save the data in the package as an .rda file with the ideal compression. See examples from other folders in data-raw for sample code. The contents of this folder do not end up in the package (the entire folder is ignored in the .Rbuildignore) so you don’t need to worry about adding package dependencies etc.
6. In the R folder, create an R script called data-name_of_dataset and add documentation using Roxygen style. See other documentation files for help with style. In the examples, use tidyverse syntax but do not use library(tidyverse) and only use the relevant packages, e.g. library(dplyr), library(ggplot2).
7. Restart R and run devtools::load_all() to make sure the data loads and run your examples to confirm they all work.
8. Run devtools::document(), restart R, and then devtools::load_all(). Then, check out ?name_of_dataset to make sure the documentation looks as expected.
9. Run devtools::check(). The only NOTE you should see as a result of the check should be about the package size. If any other ERRORs, NOTEs, or WARNINGs are generated, resolve them or open an issue for help.
10. Commit the changes made in the git tab of RStudio.
11. Run usethis::pr_push() to submit the pull request. This will open a new tab in your browser with a pull request form filled out in GitHub. Submit the request by pressing the green "Create pull request" button. After the request had been merged, run usethis::pr_finish().
12. Please DO NOT edit the description or namespace files.

Getting GitHub and RStudio to Sync

---

If you are new to GitHub and RStudio, this section will help you get them synced/talking to each other. There are instructions for Windows and Mac users. If you are a Linux user, please contact me for help; for the most part you can follow the Mac instructions but getting RTools to install is different from Mac and can even vary between Linux distributions.

If you are a better visual learner, there are screencasts linked at the bottom of this page.

Before proceeding, make sure you have your GitHub username and the email you use to login handy.

1. Setting Up Git Credentials

   A. Open the Command Prompt (Windows) or Terminal (Mac). Run each command below sequentially.

    i. git config --global user.name "your_github_user_name"
    
    ii. git config --global user.email "email_for_github_login"
    
    iii. git config --list 
    
        a. This command will confirm that the first two commands ran correctly.
   

   B. Open RStudio and run the code below in the Console.

    i. (optional) If not installed, run install.packages(c("devtools", "usethis"))
    
    ii. usethis::create_github_token()
    
        a. This will open a web browser and create a Personal Access
        Token (PAT) for your GitHub account. Copy this token. 
        
    iii. gitcreds::gitcreds_set()
    
        a. Paste the PAT when prompted
        
    iv. gh::gh_whoami()
    
        a. This will show your username, email and confirm the token saved correctly. 
   

2. Installing RTools

   A. Mac

    i. Open Terminal and run the command below.
    
        a. xcode-select --install
   

   B. Windows

    i. Go to the RTools website (https://cran.r-project.org/bin/windows/rtools).
    
    ii. Install the x-86 version of RTools
    
    iii. Open RStudio and run the code below in the Console.
    
        a. writeLines('PATH = "${RTOOLS40_HOME}\\usr\\bin; ${PATH}" ', con = "~/.Renviron")
   

   C. Mac & Windows

    i. Open RStudio and run the code below in the Console to confirm that your system is ready to build packages.
    
        a. pkgbuild::check_build_tools()
   

For those without experience using R and/or GitHub

If you would like to learn how to use R and/or GitHub, please send me an email.

If you would like to contribute without learning R or GitHub, please email your data sets in csv format. Please include the source of the data.
