xf	Vector of probability (or frequency) distribution
mt	graph title
dig	Number of digits below the decimal point (default=3)
prt	Print detailed output? Default: FALSE
plot	Plot the PDF? Default: FALSE
pos	Legend location, Default: 'topright'

Value

list(Ex=expected value, Dx=standard deviation, Vx=variance)
