...ctors and the X are matrices of different dimensions. I tried to solve this problem iteratively by the following code, but received an error message, which I do not understand: > for(i in 1:1067){ + c<-0 + for(j in 1:300){ + if(Sk[i,j]!=0){ + c<-c+1 + if(c==1){ + X1<-att[j,] + X2<-attq8[j,] + y<-Sk[i,j] + } + else{ + X1<-rbind(X1,att[j,]) + X2<-rbind(X2,attq8[j,]) + y<-rbind(y,Sk[i,j]) + } + }} + regdata1[[c(i,1)]]<-y + regdata1[[c(i,2)]]<-X1 + regdata2[[c(i,1)]]<-y + regdata2[[c(i,2)]]<-X2 + } Fehler: objekt "regdata1" nicht gefunden ??? So, doe...
