Dear Admin,
I will appreciate if you advise me an effective way to write the following R
code including nested for loops. I cannot do it by using expand.grid
function because it results with memory allocation problems.
Thanks for your time and consideration.
for(d1 in 0:n){
for(d2 in 0:n){
for(d3 in 0:n){
for(d4 in 0:n){
for(d5 in 0:n){
for(d6 in 0:n){
for(d7 in 0:n){
for(d8 in 0:n){
for(d9 in 0:n){
for(d10 in 0:n){
for(d11 in 0:n){
for(d12 in 0:n){
for(d13 in 0:n){
for(d14 in 0:n){
for(d15 in 0:n){
for(d16 in 0:n){
for(d17 in 0:n){
for(d18 in 0:n){
for(d19 in 0:n){
for(d20 in 0:n){
list=c(d1,d2,d3,d4,d5,d6,d7,d8,d9,d10,d11,d12,d13,d14,d15,d16,d17,d18,d19,d20)
}}}}}}}}}}}}}}}}}}}}
Probably not what you want, but this should replicate the same effect as
the code you posted:
list <- rep( n, 20 )
