My teaching materials and files

Some files

  • Redcap API
    • A new R function that exports data from redcap through the API within R. This function, along with new options provided by the redcap API system, applies the metadata to the data via factor levels and variable labels (in Hmisc R package). Will Gray wrote it. Thank him if you see him.
    • Scott Burns has written an introduction to redcap's API. His examples use python.
    • pdf slides about using api with R to export data from redcap from my talk for the department Statistical Computing Series
