Version Compatibility

Reference examples tested with: ggplot2 3.5+, matplotlib 3.8+, numpy 1.26+

Before using code patterns, verify installed versions match. If versions differ:

• Python: pip show <package> then help(module.function) to check signatures
• R: packageVersion('<pkg>') then ?function_name to verify parameters

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.

Volcano Plot Customization

"Create a volcano plot" → Plot log2 fold change vs -log10 p-value from differential expression results, highlighting significant genes.

• R: EnhancedVolcano::EnhancedVolcano(), ggplot2 with manual thresholds
• Python: matplotlib.scatter() with color-coded significance categories
