[R] Combining simulated data

I think this is what you want:

Hypermarket <- matrix(rnorm(10, mean=20000, sd=7000))
Supermarket <- matrix(rnorm(15, mean=12000, sd=4000))
Minimarket   <- matrix(rnorm(20, mean=10000, sd=4000))
Cornershop  <- matrix(rnorm(20, mean= 8000, sd=3000))
Spazashop   <- matrix(rnorm(35, mean= 7000, sd=3000))
rbind(Hypermarket,Supermarket,Minimarket,Cornershop,Spazashop)

This creates a matrix with one column and 100 rows.  You can add names
also by doing something like this for e.g. Spazashop
Spazashop   <- matrix(rnorm(35, mean= 7000, sd=3000), dimnames =
list(paste("Spazashop",1:35)))

Hope this helps.
