I want to populate the matrix prb through the function HWMProb <- function
(a,j,dt) that encapsulates different functions (please see code below), using
j= 0:2 for each j.
It only populates prb if I specify each function independently in the global
environment and then run the loop with the iF

I'd need to know the dimensions of your matrix
Hi Michael
testdat <- replicate( 50, growth[ sample(nrow(growth), 8, rep=TRUE) ] )
testdat will then be a matrix of 8 x 50 = 400 rows where each lot of 8
is a sample.
Alternatively you can do...
testdat <- replicate( 50, growth[ sample(nrow(growth), 8, rep=TRUE) ],
simplify=FALSE )
Now testdat
I have R randomly sampling my array made up of 2 columns of data. Here is
my code randomly sampling 5 different rows from my dataset to create a new
dataset of 8 rows of data:
testdat<-growth[sample(5,8,replace=T),]
Now I want to tell R to repeat this function 50 times and give me the
10 matches
