EWAScaller: Query and Analyse the 'EWAS Atlas' Database

Provides a client for the 'EWAS Atlas' web services (<https://ngdc.cncb.ac.cn/ewas/>; Li et al. (2019) <doi:10.1093/nar/gky1027>), allowing users to query epigenome-wide association study (EWAS) data by CpG (cytosine-phosphate-guanine) probe identifier, gene symbol, or genomic region, and to run trait, Gene Ontology, KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway, and genomic location enrichment analyses on a set of CpG probes. Query functions support concurrent, rate-limited requests to the remote service. Results are returned as tidy data frames with dedicated summary and plotting methods, including word clouds of enriched 'EWAS Atlas' trait terms.
