Create a new vignette that will support the Aug 12, 2021 R/Medicine Conference workshop organized by @higgi13425.

1. Introduce REDCap for novices
   • you probably have REDCap at your institution (w/ map & contact names)
   • test vs production projects
   • data entry validation strategies to prevent errors
   • when building an instrument/form, leverage existing standards and forms that have already been vetted by committees.
   • surveys vs conventional data entry forms
   • security & PHI
   • overview of how REDCap connects to other systems and other collaborators. Tease Kenneth's upcoming segment.
2. EMR-ish data exists in a REDCap project. A readonly API token is publically available
3. R calls REDCapR::retrieve_credential_local() to retrieve the token & URL
4. R calls REDCapR::redcap_read() and receives a data.frame.
5. An Rmd file bundles those previous two steps and produces an html document that contains
   1. A peak at the data.frame (with a warning that PHI would be exposed in a real example)
   2. Basic graphs
   3. An NIH-style table of demographics --probably using the codified package.
6. Include links to training documentation & videos. Encourage them to talk to their site's REDCap admin

(Reminder to myself, there's a Google Docs we're using to organize thoughts for workshop. Look for an email from Peter Higgins.)
