pop_data: Return or set population data bindings

In Tplyr: A Traceability Focused Grammar of Clinical Data Summary

Return or set population data bindings

Description

The population data is used to gather information that may not be available from the target dataset. For example, missing treatment groups, population N counts, and proper N counts for denominators will be provided through the population dataset. The population dataset defaults to the target dataset unless otherwise specified using set_pop_data.

Usage

pop_data(table)

pop_data(x) <- value

set_pop_data(table, pop_data)

Arguments

table	A tplyr_table object
x	A tplyr_table object
value	A data.frame with population level information
pop_data	A data.frame with population level information

Value

For tplyr_pop_data the pop_data binding of the tplyr_table object. For tplyr_pop_data<- nothing is returned, the pop_data binding is set silently. For set_tplyr_pop_data the modified object.

Examples

tab <- tplyr_table(iris, Species)

pop_data(tab) <- mtcars

tab <- tplyr_table(iris, Species) %>%
  set_pop_data(mtcars)
