abs
Absolute Value

### Description

Returns the absolute value of each element of the input.

### Usage

    abs(x)

### Arguments

x | an object with mode "logical", "numeric" or "complex". Missing values (NAs) are allowed.

### Details

This function is a member of the Math group of generic functions.
Value
returns an object like x, with the absolute value of each data value taken. If x is a complex number, its modulus is returned. That is, Mod(x).
Classes
This function is used as the default method for classes that do not inherit a specific method for the function or for the Math group of functions. The result retains the class and the attributes. If this behavior is not appropriate, the designer of the class should provide a method for the function or for the Math group,

Examples

    abs(rnorm(10)) # vector of length 10
    abs(matrix(rnorm(10), 2)) # 2 by 5 matrix
    abs(c(-2+4i, 5-3.2i))  # complex number.
    # [1] 4.472136 5.936329
    x <- rnorm(10) > 0 # logical vector
    abs(x) # result is numeric vector
