expand.grid overflows?
>cbn<-as.matrix(expand.grid( rep( list(0:1), 50)))
Error in rep.int(rep.int(seq_len(nx), rep.int(rep.fac, nx)), orep) :
invalid 'times' value
In addition: Warning message:
In rep.int(rep.int(seq_len(nx), rep.int(rep.fac, nx)), orep) :
NAs introduced by coercion
But I'm only interested in cbn matrix rows where:
cbn<- cbn[rowSums(cbn)==5,]
Is there a way to evaluate it
