wrangle_web_cdi.Rd

Clean up raw CDI output (item + summary) for any project administered through WebCDI.

Usage

wrangle_web_cdi(
  cdi_df,
  form = c("WG", "WS"),
  table = c("summary", "wordlevel", "raw"),
  withDemographic = FALSE,
  justWord = TRUE,
  rename = TRUE
)

Arguments

form

Which kind of cdi form is this (WG or WS). Will only include columns from each form.

table

Which subset of the output to include? All table include id-related columns: "study_name", "subject_id", "repeat_num".

  • "summary" (default): each row is one cdi form, including aggregated score for each form (e.g. total words produced, total number of first gestures, etc.).

  • "wordlevel": each row is an item on one cdi form, with an "item" column for the name of the item and a "response" column.

  • "raw": this is the rawest form of the data as downloaded from webcdi, with id-related columns added, each row is one cdi form, including columns for each item and columns for aggregated score, as well as metadata columns (e.g. date created, webcdi link, admin id, etc.). Is not affected by withDemographic and justWord parameters.

withDemographic

Should the data include answers to demographic questions (e.g. sibling count, birth order, caregive info, etc.)? These columns are not treated as item, so if you select wordlevel_long table, the demographic answers will be included in every row. If you select raw table, demographic columns will always be included. FALSE is default.

justWord

Should the data include only vocabulary checklist item? If TRUE (default), returns only Words Produced and Words Understood related columns for summary table and vocabulary items for wordlevel table. If FALSE, will include gestures-related items for WG form and sentence-related items for WS form. If you select raw table, all items will be included regardless of this variable.

rename

For WS form, do we standardize the name of the word-related summary item to be the same as WG form. If TRUE (default), the three summary columns in WS named Total Produced, Total Produced Percentile-sex, and Total Produced Percentile-both will changed to Words Produced, Words Produced Percentile-sex and Words Produced Percentile-both. Otherwise, they will remain unchanged

filepath

Dataframe of the csv file downloaded from WebCDI (you should use the csv with both item level and sumary data)

Value

A dataframe of the wrangled CDI output according to the parameters
