Given a numeric object, return the logit of the values. Missing values (NAs) are allowed.

logit(x)

Arguments

x

a numeric object containing values between 0 and 1

Value

An object of the same type as x containing the logits of the input values.

Details

The logit is defined by \( log(x/(1-x)) \). Values in x of 0 or 1 return logits of -Inf or Inf respectively. Any NAs in the input will also be NAs in the output.

Examples

logit(0.5)
#> [1] 0
