Les noms de ligne ne correspondent pas après la fusion

Question

J'ai 3 trames de données simples.

Je suis en train de les fusionner tous par « row.names » après la réponse ici: Merging more than 2 dataframes in R by rownames

MyMerge <- function(x, y){ 
    df <- merge(x, y, by= "row.names", all=F) 
    return(df) 
} 

Cependant, quand je regarde l'ensemble de données fusionnées, avec la nouvelle colonne créée ("Row .names '), j'ai remarqué que les nombres pour chaque rangée ne correspondent pas.

Row.names Row.names Row.names Group x x1 x2 
1 1 1 119.081.240.943.588 259.775.831.650.296 0 23.866.286.096.227 
10 106 193 118.588.864.584.922 845.466.938.787.896 0 0 
100 188 267 532.470.728.304.433 565.616.257.412.307 0 373.683.435.824.118 
1000 999 998 182.422.581.976.367 403.479.125.577.061 0 0 
101 189 268 187.528.121.080.196 812.136.181.788.992 0 20 
102 19 114 118.469.911.723.838 603.221.056.171.313 0 0 
103 190 269 152.772.529.333.869 588.104.989.185.363 0 0 

est-ce normal? et cela signifie-t-il que la fusion a bien fonctionné?

Comme demandé, voici quelques parties des data.frames:

Answer 1

merge crée une nouvelle colonne Row.names lorsqu'elles sont jointes sur rownames et les rownames sont supprimés. Soupir. Donc, mettez à jour votre fonction de fusion pour les remettre et continuer!
