Calculate crude rates

Description

calculate_cruderate performs calculations for a crude rate per 100,000 (by default) and associated standard errors. If the numerator is 0, the standard error is determined by the modified Wald interval. Missing numerator values will be filled with zero. When denominator is NA, the rates/SE will not occur.

Usage

calculate_cruderate(data, numerator, denominator, per = 1e+05)

Arguments

data	A data object.
numerator	Character vector of the column name.
denominator	Character vector of the column name.
per	Numeric value for rate scale (i.e. per X population).

Value

A new dataset (tibble) with crude rate and standard error added.

Examples

tempData <- data.frame(cases = as.numeric(c(1, 0 , 100, 10, NA)), population = as.numeric(c(10, 1000, 3200, NA, 1000)))
calculate_cruderate(tempData, 'cases', 'population')
