buildExhaustive: Prepare data for an exhaustive search

In BiocNeighbors: Nearest Neighbor Detection for Bioconductor Packages

Description

Transform data in preparation for an exhaustive (i.e., brute-force) search.

Usage

buildExhaustive(X, transposed = FALSE, distance = c("Euclidean", "Manhattan"))

Arguments

X	A numeric matrix where rows correspond to data points and columns correspond to variables (i.e., dimensions).
transposed	Logical scalar indicating whether X is transposed, i.e., rows are variables and columns are data points.
distance	String specifying the type of distance to use.

Value

An ExhaustiveIndex object containing:

• data, a numeric matrix with points in the columns and dimensions in the rows, i.e., transposed relative to the input.

• NAMES, a character vector or NULL equal to rownames(X).

• distance, a string specifying the distance metric used.

Examples

Y <- matrix(rnorm(100000), ncol=20)
out <- buildExhaustive(Y)
out
