estimateIGTProjection: Estimates an Information Geometric Temporal plot projection

Description

Estimates an IGTProjection object from a DataTemporalMap object.

Usage

estimateIGTProjection(
  dataTemporalMap,
  dimensions = 3,
  startDate = NULL,
  endDate = NULL
)
# S4 method for DataTemporalMap
estimateIGTProjection(
  dataTemporalMap,
  dimensions = 3,
  startDate = NULL,
  endDate = NULL
)

Arguments

dataTemporalMap

of class DataTemporalMap object.

dimensions

numeric integer value indicating the number of dimensions for the projection.

startDate

a Date object indicating the date at which to start the analysis, in case of being different from the first chronological date in the date column (the default).

endDate

a Date object indicating the date at which to end the analysis, in case of being different from the last chronological date in the date column (the default).

Value

An IGTProjection object containing the projected coordinates of each temporal batch in the embedded non-parametric Statistical Manifold
