...umns. I need to calculate the sum over some rows of each column separately, as follows: fa1<-(colSums(p[1:25,])) fa2<-(colSums(p[26:50,])) fa3<-(colSums(p[51:75,])) fa4<-(colSums(p[76:100,])) fa5<-(colSums(p[1:100,])) and then I need to apply to each of them the following: fa1b<-c() for (i in 1:3){ fa1b[i]<-(100-(100*abs(fa1[i]/sum(fa1[i])-(1/3)))) } fa2b<-c() for (i in 1:3){ fa2b[i]<-(100-(100*abs(fa2[i]/sum(fa2[i])-(1/3)))) } and so on. Is there a more efficient way to do this? Thanks for your time! Francesca ----------------------------------...
