propbrk {plotrix}

Calculate the proportion of specified values in a vector

Description

Calculates the proportion of values in a vector that are equal to a specified value.

Usage

 propbrk(x,trueval=TRUE,na.rm=TRUE)

Arguments

x

a character, factor or numeric vector.

trueval

the value to be matched in ‘⁠x⁠’.

na.rm

whether to remove NA values.

Details

‘⁠propbrk⁠’ calculates the proportion of values matching a specified value. It is mainly to allow proportions to be calculated in the ‘⁠brkdnNest⁠’ function. It always discards NAs in ‘⁠x⁠’ when summing the number equal to ‘⁠trueval⁠’, but respects the ‘⁠na.rm⁠’ argument when calculating the total number of values in ‘⁠x⁠’.

Value

nil
