Usage

prop(x, numerator, denominator, percent = TRUE, round = TRUE,
  digits = 1)

ratio(x, numerator, denominator, round = FALSE, digits = 1)

numerator	A vector of elements to count in the numerator.

ratio returns a ratio.

Examples

example <- c(T, T, T, T, T, F, F, F, NA)
prop(x = example, numerator = T, denominator = F)
prop(x = example, numerator = T, denominator = F, percent = FALSE, digits = 3)

ratio(example, T, F)
ratio(example, T, F, round = TRUE)
