smdi_summarize {smdi} | R Documentation |
Utility helper to give a light summary of partially observed covariates
Description
This function takes a dataframe and automatically returns the amount and proportion of missing for partially observed covariates assuming a one-row-per-patient dataframe. This is an important utility function for other functions in this package. Results can also be stratified by another variable in which case the proportion missing refers to the amount of patients in the respective stratum.
