Description

Calculate grouped case fatality

Usage

letalidade(
  dados,
  obitos,
  casos,
  grupo = NULL,
  multiplicador = 100,
  confianca = NULL,
  na_rm = FALSE,
  zero_denominador = c("na", "erro")
)

Arguments

dados	A non-empty data frame.
obitos	Name of the deaths among cases column.
casos	Name of the cases column.
grupo	Optional character vector naming grouping columns.
multiplicador	Positive scale, default 100 for a percentage.

zero_denominador	How to handle zero denominators: '"na"' returns 'NA', while '"erro"' stops.

Value

Examples

dados <- data.frame(doenca = c("A", "A"), obitos = c(1, 2),
                    casos = c(20, 30))
letalidade(dados, "obitos", "casos", grupo = "doenca")
