Discretize continuous data into bins

Converts continuous expression values to discrete bins using quantile-based or equal-width binning. Useful as a preprocessing step for the binning PMI estimator.

Usage

discretize_data(data, bins = 10, method = c("quantile", "width"))

Arguments

data

Numeric matrix or data.frame.

bins

Number of bins (default 10).

method

Binning method: "quantile" (equal frequency, default) or "width" (equal width).

Value

An integer matrix of bin indices.

Examples

set.seed(42)
dat <- matrix(rnorm(200), nrow = 20, ncol = 10)
d <- discretize_data(dat, bins = 5)
