Description

Calculate risk ratios and risk differences

Usage

risk(data, exposure, outcome, ci_level = 95)

Arguments

data	A dataframe
exposure	Variable giving the levels of the outcome
outcome	Variable giving cases (1) or non-cases (0)
ci_level	a string giving the confidence interval

Value

A dataframe with the risk ratio, risk difference and confidence intervals

Examples

# Data from stratum 1 of table 15-1., p260
dat <- data.frame(
    exposure_var = c(rep(1, 8), rep(0, 5), rep(1, 98), rep(0, 115)),
  outcome_var = c(rep(1, 8), rep(1, 5), rep(0, 98), rep(0, 115)),
  stringsAsFactors = FALSE
)
risk(data = dat, exposure = exposure_var, outcome = outcome_var)
