Hey list,
This might be a more general question and not that R-specific. Sorry for
that.
I'm trying to draw a random vector of 4 numbers that sum up to 1.
My first approach was something like
a <- runif(1)
b <- runif(1, max=1-a)
c <- runif(1, max=1-a-b)
d <- 1-a-b-c
but this kind of distorts the results, right?
Would the following be a good approach?
w <- sample(1:100, 4, replace=TRUE)
w <- w/sum(w)
I'd prefer a general algorithm-kind of answer to a specific R function
(if there is any). Although a function name would help too, if I can
sourcedive.
Thanks in advance,
Alex
