# ===============================
# test function

# load data
data(p)

# default plot
annoPoint(object = p,
          annoPos = 'top',
          xPosition = c(1:10))

# specify yPosition
annoPoint(object = p,
          annoPos = 'top',
          xPosition = c(1:10),
          yPosition = rep(c(2,4,2,6,4),each = 2))

# add right
annoPoint(object = p,
          annoPos = 'right',
          yPosition = c(1:10))

# left
annoPoint(object = p,
          annoPos = 'left',
          yPosition = c(1:10))

# supply xPosition to ajust
annoPoint(object = p,
          annoPos = 'right',
          yPosition = c(1:10),
          xPosition = 0.3)
