In LisaHopcroft/CTutils: Helpful Functions for Clinical Trial Data Analysis at SCTRU (Public Health Scotland)

Description

This function returns the number of non-empty entries, optionally for each patient and each timepoint. Ensure that the tibble provided includes ALL rows (i.e., this is the extended form of the data from MACRO, with lots of empty values). If grouping by timepoint is specified, the data will be returned with the timepoints spread as columns.

Usage

  this_data,
  this_var,
  patient_column = NULL,
  timepoint_column = NULL,
  spread_timepoints = TRUE,
  this_function = NA
)

Arguments

this_data	The tibble in which the column exists
this_var	The column name (if not a quosure, it will be made into one)
patient_column	The column name containing the patient ID to group by (default is to not group)
timepoint_column	The column name containing the timepoint to group by (default is to not group)
spread_timepoints	A column to spread the results by timepoint (default is TRUE)
