ma.vector {OLIN} | R Documentation

## Calculation of moving average for a vector

### Description

This functions calculates the moving average for a vector.

### Usage

    ma.vector(A,M,av="median",delta=50)

### Arguments

`A` | vector of predictor to be used for sorting
`M` | vector of variable to be averaged
`av` | averaging by mean or median (default)
`delta` | even integer determining the size of the sliding window (`2*delta+1`.)

### Details

The function `ma.vector` first sorts M according to the corresponding values of A. Subsequently, a moving average is calculated with window size (`2*delta+1`). The values for the moving average are set to zero if the corresponding window extends over the boarder of the vector `M`.

### Value

Vector with moving average values of `M`

    ### LOADING DATA
    data(sw)
    A <- maA(sw[,1])
    M <- maM(sw[,1])

    # MA-PLOT
    plot(A,M)

    # MOVING AVERAGE
    Mav <- ma.vector(A,M,av="median",delta=100)
    points(A,Mav,col="red")
