random discrete from the first tuple
Dear UseR
I have a dataset, for instance x1(A, B, C), x2(M,F), x3(X1,X2,X3,X4)
and x4(W,F,P). I want to make a small dataset with the random tuple. I
know package e1071 can handle a random discrete,
> library(e1071)
> x1 <- rdiscrete(6, c(2,2,2), c("A","B","C"))
> x2 <- rdiscrete(6, c(3,3), c("M","F"))
> x3 <- rdiscrete(6, c(2,2,1,1), c("X1","X2","X3","X4"))
> x4 <- rdiscrete(6, c(2,2,2), c("W","F&...

Efficient sampling from a discrete distribution in R
Hello r-help,
As far as I've seen, there is no function in R dedicated to sampling
from a discrete distribution with a specified mass function. The
standard library doesn't come with anything called rdiscrete or rpmf,
and I can't find any such thing on the cheat sheet or in the
Probability Distributions chapter of _An Introduction to R_. Googling
also didn't bring back anything. So, here's my first attempt at a
solution. I'm hoping someone here knows of a more efficient way.

Discrete random variable
Hi,
I would create a function rdiscrete that returns the value of a discrete random
variable X defined on a subset which can change, and for the same probability for
the issue, eg:
X could sometimes take a value in the subset {2,3,4} with probability 1/3 for each
issue,
and sometimes X could take a value in the subset {2,3,4,5,6} with p...
