profile2fd: Transform distribution and concentration profiles to...

In trackerproject/trackeR: Infrastructure for Running, Cycling and Swimming Data from GPS-Enabled Tracking Devices

Transform distribution and concentration profiles to functional data objects of class fd.

Description

Transform distribution and concentration profiles to functional data objects of class fd.

Usage

profile2fd(object, what, ...)

Arguments

object	An object of class distrProfile or conProfile, as returned by distributionProfile and concentrationProfile, respectively.
what	The variable for which the profiles should be transformed to a functional data object.
...	Additional arguments passed on to Data2fd

Value

An object of class fd.

Examples

## Not run: 
library('fda')
data('runs', package = 'trackeR')
dp <- distributionProfile(runs, what = 'speed')
dpFun <- profile2fd(dp, what = 'speed',
    fdnames = list('speed', 'sessions', 'time above threshold'))
dp.pca <- pca.fd(dpFun, nharm = 4)
## 1st harmonic  captures vast majority of the variation
dp.pca$varprop
## time spent above speed = 0 is the characteristic distinguishing the profiles
plot(dp.pca, harm = 1)
sumRuns <- summary(runs)
plot(sumRuns$durationMoving, dp.pca$scores[,1])

## End(Not run)
