attachLabels(vo, cat = c(vo$A$label, vo$B$label), cat.labelpos = NULL,
  cat.angle = NULL, cat.pos = c(vo$A$pos, vo$B$pos),
  cat.offset = c(vo$A$offset, vo$B$offset))

`vo`	- vennobject.
`cat`	- character vector. Two labels for circles A and B
`cat.labelpos`	-
`cat.angle`	- if absolute position is not specified, can specify angle (in radians) from center 0 corresponds to label just above the circle.
`cat.pos`	- a vector with four items (adjA, adjA, adjB, adjB) use this with cat.angle to tune where label appears relative to the anchor position
`cat.offset`	- numeric vector, distance of labels from
