Hi all,

I want to make all possible combination from dataset below:

V1 <- c(0,1,2) V2 <- c(0,1) V3 <- c(0,1) V4 <- c(0,1) V5 <- c(0,1) V6 <- c(0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20) V7 <- c(0,1,2,3,4,5,6) V8 <- c(0,1) V9 <- c(0,1) V10 <- c(0,1) V11 <- c(0,1) V12 <- c(0,1) V13 <- c(0,1) V14 <- c(0,1) V15 <- c(0,1,2,3,4,5,6,7,8,9) V16 <- c(0,1,2,3,4,5,6) V17 <- c(0,1,2,3,4,5,6,7,8) V18 <- c(0,1,2,3,4,5) V19 <- c(0,1) V20 <- c(0,1,2,3,4,5,6,7)

When run expand.grid I found a problem:

* > all.V <-
*

expand.grid(V1,V2,V3,V4,V5,V6,V7,V8,V9,V10,V11,V12,V13,V14,V15,V16,V17,V18,V19,V20)
Error in rep.int(rep.int(x, rep.int(rep.fac, nx)), orep) :

invalid number of copies in rep()
In addition: Warning message:

NAs introduced by coercion

* >
*

Then I try to reduce:

* > all.V.miss <-
*

expand.grid(V1,V2,V3,V4,V5,V7,V8,V9,V10,V11,V17,V18,V19,V20)
Error: cannot allocate vector of size 36288 Kb

What is that? Is this about memory or I must run on machine 64bit?

Regards, Muhammad Subianto
