In addition to the unadjusted pathway correlations, this package provides those that were adjusted to account for the shared genes between pathway pairs \section{Using pcxnData with pcxn package} The data in this package are primarily used by the pcxn package. For the following examples to work, the pcxn package needs to be installed. For further explanations of some of the functions mentioned in the examples please refer to pcxn. <<>>= # Use the pcxn library library(pcxn) library(pcxnData) # Load the data ds = c("cp_gs_v5.1", "gobp_gs_v5.1", "h_gs_v5.1","pathprint.Hs.gs", "pathCor_CPv5.1_dframe","pathCor_GOBPv5.1_dframe","pathCor_Hv5.1_dframe", "pathCor_pathprint_v1.2.3_dframe","pathCor_CPv5.1_unadjusted_dframe", "pathCor_GOBPv5.1_unadjusted_dframe","pathCor_Hv5.1_unadjusted_dframe", "pathCor_pathprint_v1.2.3_unadjusted_dframe") data(list = ds) # Explore the static extendable network by focusing on single pathways and their # 10 most correlated neighbours in the pathprint collection pcxn.obj <- pcxn_explore(collection = "pathprint", query_geneset = "Alzheimer's disease (KEGG)", adj_overlap = FALSE, top = 10, min_abs_corr = 0.05, max_pval = 0.05) # Analyse relationships between groups of pathways shown to be enriched in the # collection by gene set enrichment pcxn.obj <- pcxn_analyze(collection = "pathprint", phenotype_0_genesets = c("ABC transporters (KEGG)", "ACE Inhibitor Pathway (Wikipathways)", "AR down reg. targets (Netpath)"), phenotype_1_genesets = c("DNA Repair (Reactome)"), adj_overlap = FALSE, top = 10, min_abs_corr = 0.05, max_pval = 0.05 ) # Generate the heatmap for any pcxn object generated by the # explore or analyze function hm <- pcxn_heatmap(pcxn.obj , cluster_method = "complete") # Get the gene members (Entrez Ids and symbols) of any pathway/geneset in the # data gene_members <- pcxn_gene_members(pathway_name = "Alzheimer's disease (KEGG)") @ \end{document}
