Arguments

analyteLists	vector of the ID type of the corresponding interesting analyte list. The supported ID types of WebGestaltR for the selected organism can be found by the function listIdType. If the organism is others, users do not need to set this parameter. The length of analyteLists should be the same as the length of analyteListFiles or analyteLists.
analyteListFiles	If enrichMethod is ORA, the extension of the analyteListFiles should be txt and each file can only contain one column: the interesting analyte list. If enrichMethod is GSEA, the extension of the analyteListFiles should be rnk and the files should contain two columns separated by tab: the analyte list and the corresponding scores.
analyteTypes	a vector containing the ID types of the analyte lists.
enrichMethod	Enrichment methods: ORAor GSEA.
organism	Currently, WebGestaltR supports 12 organisms. Users can use the function listOrganism to check available organisms. Users can also input others to perform the enrichment analysis for other organisms not supported by WebGestaltR. For other organisms, users need to provide the functional categories, interesting list and reference list (for ORA method). Because WebGestaltR does not perform the ID mapping for the other organisms, the above data should have the same ID type.
enrichDatabase	The functional categories for the enrichment analysis. Users can use the function listGeneSet to check the available functional databases for the selected organism. Multiple databases in a vector are supported for ORA and GSEA.
enrichDatabaseFile	Users can provide one or more GMT files as the functional category for enrichment analysis. The extension of the file should be gmt and the first column of the file is the category ID, the second one is the external link for the category. Genes annotated to the category are from the third column. All columns are separated by tabs. The GMT files will be combined with enrichDatabase.
enrichDatabaseType	The ID type of the genes in the enrichDatabaseFile. If users set organism as others, users do not need to set this ID type because WebGestaltR will not perform ID mapping for other organisms. The supported ID types of WebGestaltR for the selected organism can be found by the function listIdType.
enrichDatabaseDescriptionFile	Users can also provide description files for the custom enrichDatabaseFile. The extension of the description file should be des. The description file contains two columns: the first column is the category ID that should be exactly the same as the category ID in the custom enrichDatabaseFile and the second column is the description of the category. All columns are separated by tabs.
collapseMethod	The method to collapse duplicate IDs with scores. mean, median, min and max represent the mean, median, minimum and maximum of scores for the duplicate IDs.
minNum	WebGestaltR will exclude the categories with the number of annotated genes less than minNum for enrichment analysis. The default is 10.
maxNum	WebGestaltR will exclude the categories with the number of annotated genes larger than maxNum for enrichment analysis. The default is 500.
fdrMethod	For the ORA method, WebGestaltR supports five FDR methods: holm, hochberg, hommel, bonferroni, BH and BY. The default is BH.
sigMethod	Two methods of significance are available in WebGestaltR: fdr and top. fdr means the enriched categories are identified based on the FDR and top means all categories are ranked based on FDR and then select top categories as the enriched categories. The default is fdr.
fdrThr	The significant threshold for the fdr method. The default is 0.05.
topThr	The threshold for the top method. The default is 10.
reportNum	The number of enriched categories visualized in the final report. The default is 20. A larger reportNum may be slow to render in the report.
setCoverNum	The number of expected gene sets after set cover to reduce redundancy. It could get fewer sets if the coverage reaches 100%. The default is 10.
perNum	The number of permutations for the GSEA method. The default is 1000.
gseaP	The exponential scaling factor of the phenotype score. The default is 1. When p=0, ES reduces to standard K-S statistics (See original paper for more details).
isOutput	If isOutput is TRUE, WebGestaltR will create a folder named by the projectName and save the results in the folder. Otherwise, WebGestaltR will only return an R data.frame object containing the enrichment results. If hundreds of gene list need to be analyzed simultaneously, it is better to set isOutput to FALSE. The default is TRUE.
outputDirectory	The output directory for the results.
projectName	The name of the project. If projectName is NULL, WebGestaltR will use time stamp as the project name.
dagColor	If dagColor is binary, the significant terms in the DAG structure will be colored by steel blue for ORA method or steel blue (positive related) and dark orange (negative related) for GSEA method. If dagColor is continous, the significant terms in the DAG structure will be colored by the color gradient based on corresponding FDRs.
saveRawGseaResult	Whether the raw result from GSEA is saved as a RDS file, which can be used for plotting. Defaults to FALSE. The list includes Enrichment_Results A data frame of GSEA results with statistics Running_Sums A matrix of running sum of scores for each gene set Items_in_Set A list with ranks of genes for each gene set
gseaPlotFormat	The graphic format of GSEA enrichment plots. Either svg, png, or c("png", "svg") (default).
nThreads	The number of cores to use for GSEA and set cover, and in batch function.
cache	A directory to save data cache for reuse. Defaults to NULL and disabled.
hostName	The server URL for accessing data. Mostly for development purposes.
useWeightedSetCover	Use weighted set cover for ORA. Defaults to TRUE.
useAffinityPropagation	Use affinity propagation for ORA. Defaults to FALSE.
usekMedoid	Use k-medoid for ORA. Defaults to TRUE.
kMedoid_k	The number of clusters for k-medoid. Defaults to 25.
isMetaAnalysis	whether to perform meta-analysis. Defaults to TRUE. FALSE is not currently implemented.
mergeMethod	The method to merge the results from multiple omics (options: mean, max). Only used if isMetaAnalysis = FALSE. Defaults to mean.
normalizationMethod	The method to normalize the results from multiple omics (options: rank, median, mean). Only used if isMetaAnalysis = FALSE.
listNames	The names of the analyte lists.
