allanvar (version 1.1)

plotav: Allan Variance plot

Description

This function plot the Allan variance graph. That is the Allan deviation $\sigma(\tau)$ against the cluster time $\tau$

Usage

plotav(avdf)

Arguments

avdf

data.frame with the results after calculating the Allan variance using avar, avarn or avari

Value

• Allan variance plot: Log-Log plot of the standard deviation $\sigma(\tau)$ against the cluster times.

Details

plotav has been developed in order to plot the Allan variance estimation in an easy way but for sure other plot functions and stronger R graphics capabilities could also be used in order to visualize the slopes.

Examples

#Load data 
data(gyroz)

#Allan variance computation using avar
avgyroz <- avar(gyroz@.Data, frequency(gyroz))
plotav(avgyroz)
