Calculate the proportion of specified values in a vector

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
