rmixnorm: Generate mixed normal random number.

In feiyoung/simutool: Common Tool Functions In Simulation

Description

Random generation for the mixed normal distribution with mixed probability equal to P, mean vector equal to vmu and standard deviation vector equal to vsigma.

Usage

Arguments

n	a positive integer, the number of random numbers.
P	a vector, the mixed probability vector.
vmu	a vector, the corresponding mean vector.
vsigma	a vector, the corresponding sd vector.

Value

Return a vector with length equal to n.
