Usage
VennMapper(data, varname, cutoff)
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
Value
An object of class VennMapper.res containing
conting.tab
A contingency table with numbers of overlapping genes in pairs of the datasets
z.score
A table of z-scores describing the significance of overlap in pairs of the datasets
genes
A table of gene names that overlap in pairs of the datasets
