NiceVennDiagram draws a Venn diagram for up to five sets and returns a data.frame with pattern frequencies and proportions.

NiceVennDiagram is a wrapper function for gplots::venn. It draws a Venn diagram and returns a data.frame with pattern frequencies and proportions. The patterns are sorted by combinatorically. Cases with any missing set indicators are discarded with an appropriate warning.

NiceVennDiagram(BINARY_SET_INDICATORS, PLOT = T, SORT_BY_FREQ = F)

Arguments

BINARY_SET_INDICATORS

data.frame of binary indicators of class logical or binary numeric 0 / 1
PLOT

= T generate a plot
SORT_BY_FREQ

= F sort patterns by frequency, not combinatorically

Value

a data.frame with pattern frequencies and proportions
