check_dm: Check binary variables

In vigicaen: 'VigiBase' Pharmacovigilance Database Toolbox

Check binary variables

Description

Quick check that your data management steps through add_adr or add_drug found cases.

Usage

check_dm(.data, cols)

Arguments

.data	A data.frame to be checked
cols	A character vector, name of columns to look at (usually will be d_names, a_names)

Details

It is a simple wrapper around dplyr::summarise(). Be careful not to supply factors with > 2 levels or continuous outcome (the function does NOT have a checker for this, so that it is faster). Also, the function WONT work with NAs. Use desc_facvar(). if you need more detailed description of your dataset.

Value

A transposed data.frame, with row.names equal to cols, and first column is the number of lines in .data where each col is equal to 1.

desc_facvar(), add_adr(), add_drug()

Examples

# first create some new variables

demo <- demo_

demo <-
  demo |>
    add_adr(
      a_code = ex_$a_llt,
      adr_data = adr_
    )

 # then check the number of reports with each feature

demo |>
  check_dm(names(ex_$a_llt))
