embed_ts: Construct an Embedded Timeseries

Description

Embeds timeseries given an embedding dimension (`E`) and a time lag (`tau`).

Usage

embed_ts(X, E, tau = 1, sample_times = NULL)

Value

A matrix where the first column is last time index of the window and the second column is the estimated index value.

Arguments

X

A numeric matrix of species abundances, names across columns, time across rows. The first column is a time vector, the remainder are species values.

E

Numeric. Embedding dimension.

tau

Numeric. Time lag.

sample_times

Numeric vector. Defines the time indices to subset prior to embedding.

Examples

#Load the multivariate simulated
#dataset `simTransComms`

data(simTransComms)

#Embed one timeseries by 5 time points

eg_embed <- embed_ts(X = simTransComms$community2[,2:3],
E = 5, tau = 1)
