May be this helps:


Dear all, 

I'm trying to generate a matrix dataset following 2 loops analysis, such as the follows: 

for (i in 1:10)  { 

k1 <- 0.3 x i 

for (j in 1:10)  { 

k2 <- j 

k3 <- k1*k2 



I would like to generate a dataset with each row containing k1, 
k2, and corresponding k3. As there's 100 combination of k1 and k2, so 
there would be 100 rows data.  how could I do it? 

Thanks for the help.
