intervalMeans

Given a matrix of normalized signal intensities and the inverse of the
corresponding structure matrices, <code>intervalMeans</code> returns the sample
mean signal intensity of each genomic interval.

Chromatin immunoprecipitation followed by high-throughput
sequencing (ChIP-seq) is the premier technology for profiling genome-wide
localization of chromatin-binding proteins, including transcription
factors and histones with various modifications.
This package provides a robust method for normalizing ChIP-seq
signals across individual samples or groups of samples. It also designs
a self-contained system of statistical models for calling differential
ChIP-seq signals between two or more biological conditions as well as
for calling hypervariable ChIP-seq signals across samples. Refer to
Tu et al. (2021) <doi:10.1101/gr.262675.120> and
Chen et al. (2022) <doi:10.1186/s13059-022-02627-9>
for associated statistical details.
