Filter genes based on expression variance to select the most dynamically expressed genes.
Usage
genes_filter_dynamic(e, thr = 0.9)
Arguments
- e
Matrix of expression values with genes as rows and samples as columns
- thr
Threshold quantile for variance filtering (default: 0.9)
Value
Matrix containing only genes above the variance threshold
Details
This function calculates the variance for each gene across samples and retains
only genes with variance above the specified quantile threshold. This helps
focus analysis on genes that show significant expression changes.
Examples
# Filter top 10% most variable genes
# filtered_expr <- genes_filter_dynamic(expression_matrix, thr = 0.9)
