Dear R users I want change the entries in a matrix. I did a matrix
A=0 1 5 .3 0 0 0 .5 0 A1<-A A2<-A*0.90 A2 1 2 3 1 0.00 0.90 4.5 2 0.27 0.00 0.0 3 0.00 0.45 0.0 I need replace elements one by one in a loop I tried the following using package POPBIO, total <-matrix(0, nrow=5, ncol=60) for(i in 1:10){ A1<-A A1[1,2] <- A2[1,2] A1[1,3]<-A2[1,3] A1[2,1]<-A2[2,1] A1[3,2]<-A2[3,2] n <-runif(3) n <- n/sum(n) p1<-pop.projection(A1,n,60) total[i,] <- p1$pop.sizes} matplot2(total, legend=NA,xlab=c(years)) but i not view change in population Thanks in advance Fidel M.
