Arguments

enrichDF

data.frame representing gene set enrichment results.

pvalueCutoff

numeric value range 0 to 1, to define the P-value threshold for enrichment results to be considered in downstream processing.

pAdjustMethod

character string to define the P-value adjustment method, or "none" for no additional adjustment. See stats::p.adjust() for valid values.

keyColname

character value of the colname(enrichDF) containing the unique row identifier. It can be a pathway_ID or any uniquely identifying value.

pathGenes

character or value of the colname(enrichDF) containing the number of genes in each pathway. This value will be derived from geneRatioColname if needed.

geneColname

character value of the colname(enrichDF) containing delimiited genes in each pathway.

geneHits

character value of the colname(enrichDF) containing the integer count of the gene hits in each pathway. This value will be derived from geneRatioColname if needed.

geneRatioColname

character value of the colname(enrichDF) containing the character ratio of gene hits to pathway size, in format "50/100". This value is used when either "pathGenes" or "geneHits" are not supplied.

geneDelim

character regular expression pattern used to separate genes in the pathGenes column into a vector of character values.

pvalueColname

character value of the colname(enrichDF) containing enrichment P-values to use in downstream processing.

msigdbGmtT

optional gmtT object, a representation of arules::transactions-class. (Not currently implemented.)

verbose

logical indicating whether to print verbose output.

...

additional arguments are ignored.

Details

This function takes a data.frame containing gene set enrichment results, and converts it to a proper enrichResult object, compatible with methods provided by the clusterProfiler package.
