buildExhaustive {BiocNeighbors} | R Documentation

## Prepare data for an exhaustive search

### 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
