Version Compatibility

Reference examples tested with: ggplot2 3.5+, scanpy 1.10+

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.

Cell-Cell Communication Analysis

"Infer cell-cell communication from my scRNA-seq data" → Predict ligand-receptor interactions between cell types and visualize intercellular signaling networks.

• R: CellChat::createCellChat() → computeCommunProb() → netAnalysis()
• Python: liana.method.cellchat() (LIANA framework)
