The RDI package is part of the Immcantation analysis framework for Adaptive Immune Receptor Repertoire sequencing (AIRR-seq) and provides an methods for visualizing and calculating the Repertoire Dissimilarity Index (RDI).
The Repertoire Dissimilarity Index is a non-parametric method for directly comparing sequencing repertoires, with the goal of rigorously quantifying differences in V, D, and J gene segment utilization. This method uses a bootstrapped subsampling approach to account for variance in sequencing depth, and, coupled with a data simulation approach, allows for direct quantification of the average variation between repertoires.
RDI version 1.0.0 is available on CRAN. You can find additional details about the package at: https://cran.r-project.org/package=rdi
