Hi, R-helpers,
I'm trying to use R to do a Monte Carlo simulation and need the
help. What I
have is a matrix that consists of the probabilities for the persons to
choose zones. For example, in the matrix shown below, each column
represents
a person, and each row represents a zone. So, the probability that
the first
person will choose the 2nd zone is 30%.
25% 30% 10% 30% 20% 0% 20% 50% 60% 50% 0% 10% 20% 0% 20%
As Alex Trebeck would say: Can you put that in the form of an R data
object?
Based on this matrix, I want to locate the persons to zones based on
the
probability using a Monte Carlo method. The result I want to see is
like
this:
0 0 0 0 0 0 0 1 1 1 0 0 0 0 0
Could anyone please give some help? Thanks.
You cannot specify what the result _will_ be and call the process
simulation of results at the same time. The sample function should
work for a vector. Why not use it?
