# negative: Apply method to Positive and Negative number In Rfast: A Collection of Efficient and Extremely Fast R Functions

## Description

Apply method to Positive and Negative number.

## Usage

 ```1 2 3``` ```negative(x,method = "min") positive(x,method = "min") positive.negative(x,method = "min") ```

## Arguments

 `x` A numerical vector with data. `method` Accept 3 values. "min", "max", "min.max".

## Details

These functions apply the chosen method to the chosen subset (negative, positive, or both) from the vector and return the result.

## Value

negative: apply the chosen method to every negative number of the input vector. positive: apply the chosen method to every positive number of the input vector. positive.negative: apply the chosen method to every negative and positive number of the input vector.
