Chapter 3 Built-in Datasets
We also have curated tens of tumor non-omics annotation datasets with supplementary features from UCSC Xena repository or other resources for extensive analysis. Notably, datasets with large amounts of data are uploaded to Zenodo. They can be loaded via load_data() function.

The immune infiltrations are estimated by immunedeconv package, where 7 types of algorithms (CIBERSORT, CIBERSORT-ABS, EPIC, MCPCOUNTER, QUANTISEQ, TIMER, XCELL) are adopted.
The expression scores for 3 type of gene pathway/signature sets (HALLMARK, KEGG, IOBR) is calculated through ssGSEA method.
