[R] hi hi, I have a problem to use union function because one of the elements is a character and the others are numeric  > for(j in 1:length(I)) { + C1 <- levels(factor(subset(donParEssai, Id_Essai == 1006961 & Id_Cara == I[j], select = Date_O)[,1])) + C2 <- as.numeric(levels(factor(subset(donParEssai, Id_Essai == 1006961 & Id_Cara == I[j], select = Stade_O)[,1]))) + C3 <- length(as.numeric(levels(factor(subset(donParEssai, Id_Essai == 1006961 & Id_Cara == I[j], select = Id_Geno)[,1])))) + C4 <- length(levels(factor(subset(donParEssai, Id_Essai == 1006961 & Id_Cara == I[j], select = Id_Rep)[,1]))) + C5 <- mean(as.numeric(as.character(subset(donParEssai, Id_Essai == 1006961 & Id_Cara == I[j], select = Val_O)[,1]))) + C6 <- range(as.numeric(as.character(subset(donParEssai, Id_Essai == 1006961 & Id_Cara == I[j], select = Val_O)[,1]))) + C7 <- sd(as.numeric(as.character(subset(donParEssai, Id_Essai == 1006961 & Id_Cara == I[j], select = Val_O)[,1]))) + RecapCara[j,] <- union(C1,union(C2,union(C3,union(C4,union(C5,union(C6,C7)))))) + } Erreur dans RecapCara[j, ] <- union(C1, union(C2, union(C3, union(C4, union(C5,  :          le nombre d'objets ï¿½ remplacer n'est pas multiple de la taille du remplacement > print(RecapCara)      [,1] [,2] [,3]     [,4] [,5] [,6]     [,7] [1,]   NA   21    3  7.66129  5.2 17.1 2.318801 [2,]   NA   21    3 50.56774 47.3 53.9 1.469222 > C1 [1] "29/08/2005" I can't paste C1 with others values how could I do to paste C1 with others please?        ___________________________________________________________________________ 	[[alternative HTML version deleted]]
