R package for detection of differentially methylated regions with adjustment for multiple testing

Important Info

Authors

CM Page, L Vos, BK Andreasen

Package structure

The function DMRScan() requires three key inputs;

• a vector of test statistics for each CpG site,
• the corresponding positions (chromosome and bp position).

Additional inputs are the

• maximum allowed distance within a region
• the minimum number of CpGs within a region.

Installation

For a stable release from Bioconductor use

if (!requireNamespace("BiocManager", quietly=TRUE))
    install.packages("BiocManager")
BiocManager::install("DMRScan")

For the developmental version from Github, use

devtools::install_github("christpa/DMRScan")

Requred R-packages for DMRScan are:

• Matrix
• MASS
• RcppRoll
• GenomicRanges
• IRanges
• methods
• mvtnorm
• stats
• parallel
