rDiscrete | R Documentation |
Generates random data from a given empirical probability function. It also returns cumulative distribution function corresponding to the entered probability function.
rDiscrete(n = 1, pf)
n |
number of observations. |
pf |
empirical probability function. |
pf
is an array of any dimensionality with all elements sum up to one. If its dimension is greater than one, it is transformed to a row vector column-by-column.

# or pf would be entered as a three dimensional array:
p = array(c(0.23,0.11,0.05,0.03,0.31,0.03,0.22,0.02), dim=c(2,2,2))
