This is a wrapper function for meta-analysis using VennMapping method. It performs all necessary steps and provides all available outputs.
Usage
VennMapper(data, varname, cutoff, ngenes)
Arguments
data
MetaArray object
varname
Character String - name of one column in clinical data matrices to be used as class labels
cutoff
Numeric - cutoff for selection of genes according to their fold-change in log2-scale. e.g. 1 equals to two-fold expression change
ngenes
Numer of genes involved in the analysis
Value
An object of class VennMapper.res containing
conting.tabA contingency table with numbers of overlapping genes in pairs of the datasets
z.scoreA table of z-scores describing the significance of overlap in pairs of the datasets
genesA table of gene names that overlap in pairs of the datasets
