I wanna display some data which there are subsets of a dataframe called "don" but there are errors like this
> L=as.numeric(levels(factor(don$Id_Cara))) > for(i in L){ + donC(i)=subset(don, Id_Cara == i, select = c( Id_TrT1, Id_Geno, Id_Rep, Val_O)) + donC(i) + } Erreur dans donC(i) = subset(don, Id_Cara == i, select = c(Id_TrT1, Id_Geno, : impossible de trouver la fonction "donC<-" I understand that the problem comes from the third line it doesn't reconize "donC(i)" but it's very important to make one "boucle" (in french) on the L's elements. to tell more about L : > L [1] 103 137 138 177 193 308 ___________________________________________________________________________ [[alternative HTML version deleted]] ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
