cutoff {eeptools} | R Documentation |
This function tells us how far we have to go before reaching a cutoff in a variable by sorting the vector, then finding how far to go. Note that the cutoff is expressed in percentage terms (fixed cumulative sum)
cutoff(x, cutoff, na.rm = TRUE)
x |
a numeric vector, missing values are allowed |
cutoff |
a user defined numeric value to stop the cutoff specified as a proportion 0 to 1 |
na.rm |
logical, should missing values be excluded? |
Calculates the distance through a numeric vector before a certain proportion of the sum is reached by sorting the vector and calculating the cumulative proportion of each element
An integer for the minimum number of elements necessary to reach cutoff

# for vector
a <- rnorm(100, mean=6, sd=1)
cutoff(a, .7) #return minimum number of elements to account 70 percent of total
