pma {shelltrace}

Function to do an n-point moving average

Description

Performs a moving average smoothing on a data series. de Winter, N. J. (2017) <doi:10.5194/gmd-2017-137>

Usage

pma(x, i, n)

Arguments

x

A numeric data frame containing the data set to be smoothed, X-values should be in the first column

i

The index of the column that contains the Y-values

n

Integer N-value determining the window size of the moving average smoothing

Value

A numeric data frame containing three columns: One with X-values, one with Y-values and one with smoothed Y-values
