[R] hello hello, I have a problem with a R program I don't understand my errors my program looks like this > for(i in LE) { +    for(j in LEC[[i]]) { +                for(k in LR) { +                         donRep[[k]] <- subset(don2, Id_Essai == 1006961 & Id_Cara == j & Id_Rep == k  & Id_Geno != 65125, select = Val_O) +                         M[[j]] <- matrix(rep(1, 3*length(donRep[[1]][,1])), nrow =length(donRep[[1]][,1]), ncol = 3) +                        for(k in LR) { +              M[[j]][,k] <- as.numeric(as.character(donRep[[k]][,1])) +                } +                         } +                print(M[[j]]) +                if (subset(donParCara, Id_Cara == j , select = Ana_C) == "AV") +               {print(cor(M[[j]], method = "pearson"))}  else{print(cor(M[[j]], method = "spearman"))} + } +       } Erreur dans M[[j]][, k] <- as.numeric(as.character(donRep[[k]][, 1])) :          le nombre d'objets ï¿½ remplacer n'est pas multiple de la taille du remplacement and sometimes it run good but sometimes there are errors I don't understand why. Can you help me please?        ___________________________________________________________________________ 	[[alternative HTML version deleted]]
