Hello R users, I would like to reduce the number of for loops in my code. I build these matrices (50000 times). The main diagonal are 1s and the two sides along the main diagonal mirror each other as follows:
i<-5 fi<-matrix(0,nrow=i,ncol=i)#floral inhibition matrix for(r in 1:i){ for(c in 1:i){ if(r==c){ fi[r,c]<-1 }else if(r<c){ fi[r,c]<-1-runif(1)^.5 }else{ fi[r,c]<-fi[c,r] } } } fi Any thoughts?
