HeatmapR: R Code for Metabolomics Peak Area Heatmaps

R code and processed spreadsheet data for creating heatmaps from metabolomics peak area data. The data were downloaded from the GNPS2 Analysis Status Page for LC-MS/MS acquisition modes and processed into a simplified format. Authored by Vlastimil Novak and last updated on June 1, 2026.

Use Cases

• Generate heatmaps for metabolomics data visualization based on peak area data.
• Process and standardize feature quantification files from GNPS2 for analysis.
• Create simplified sample-feature matrices for downstream statistical analysis.

Strengths

• Includes the original R code for reproducibility.
• Data is provided in a processed spreadsheet format (XLSX).
• Released under a permissive CC-BY-4.0 license.

Limitations

• Row and column counts are unknown, which limits suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
