sparseMatrixStats

sparseMatrixStats provides high-performance functions for row and column summary statistics on sparse matrices.

Key Features:

• Row and Column Operations: Computes summary statistics including rowMeans2, rowMedians, rowVars, colMeans2, colMedians, and colVars for sparse matrices.
• Column Sparse Format Optimization: Performance optimizations are currently limited to data in column sparse format.

Scientific Applications:

• Sparse Matrix Analysis: Enables efficient computation of summary statistics on sparse matrices commonly encountered in large-scale biological data analysis.

Methodology:

The package implements optimized algorithms for row and column operations specifically tailored to column sparse matrix representations, building upon approaches from the matrixStats package by Henrik Bengtsson.
