Data Preparation

Prepare time series for ecological memory analyses.

alignTimeSeries() mergePalaeoData(): Align and join multiple time series to a common temporal resolution
lagTimeSeries() prepareLaggedData(): Create lagged versions of time series variables

Ecological Memory Analysis

Analyze ecological memory in environmental time series.

computeMemory(): Quantifies ecological memory with Random Forest.
extractMemoryFeatures(): Extracts ecological memory features from the output of computeMemory.
plotMemory(): Plots output of computeMemory

Integration With `virtualPollen`

Perform large experiments from simulations generated with the package virtualPollen.

experimentToTable(): Turns the outcome of runExperiment into a long table.
plotExperiment(): Plots the output of runExperiment.
runExperiment(): Computes ecological memory patterns on simulated pollen curves produced by the virtualPollen package.
