This vignette is the landing page for omics-related utilities in Rtoolset. It provides a short overview of the available helpers and points to the more focused RNA-seq and DNA methylation tutorials.

Overview

Rtoolset currently includes lightweight helpers for a few common preprocessing tasks across omics workflows:

  • filtering and normalizing RNA-seq count matrices
  • log transformation and feature ranking
  • converting DNA methylation beta values to M values

These functions are designed to plug into larger workflows built with packages such as edgeR and limma.

Available Tutorials

RNA-seq Utilities

The RNA-seq tutorial covers:

See the RNA-seq Utilities vignette for examples and a suggested preprocessing workflow.

DNA Methylation Utilities

The DNA methylation tutorial focuses on:

  • beta2M() for converting beta values to M values

See the DNA Methylation Utilities vignette for examples, the conversion formula, and downstream analysis notes.

Function Map

Function Typical use
filter_calcpm_dge() RNA-seq filtering, normalization, and CPM workflow
log_transform() Custom log transformation of count-like data
get_top_var_mat() Selecting highly variable features for exploration
beta2M() Converting methylation beta values to M values

Choosing a Tutorial

  • Start with RNA-seq Utilities if you are working with raw count matrices.
  • Start with DNA Methylation Utilities if you are working with beta values from methylation assays.
  • Return to this page when you want a compact overview of omics-related helpers in the package.
