local_biplot: Create local biplot axes

In jfukuyama/localBiplots: Local biplots for multi-dimensional scaling

Create local biplot axes

Description

Create local biplot axes

Usage

local_biplot(
  X,
  dist,
  dist_deriv = NULL,
  k = 2,
  samples = 1:nrow(X),
  new_points = list()
)

Arguments

X	A data matrix, samples as rows.
dist	Either a string describing one of the supported distances or a function that takes a matrix and returns the distances between the rows of the matrix.
dist_deriv	Either NULL (if dist is a string describing one of the supported distances) or a function that takes two vectors and computes \frac{\partial}{\partial y_j}d(x,y).
k	The number of embedding dimensions.
samples	The samples to compute local biplot axes at. Defaults to all of the original samples.
new_points	New points (not one of the original samples) to compute local biplot axes at.

Value

A data frame. Each row describes one LB axis for one sample. Columns labeled 'Embedding' give the embedding of the sample in MDS space, columns labeled 'Axis' give the LB axis for a given sample and variable. Columns labeled 'variable' and 'sample' give the variable and sample for the LB axis values.
