Dear all, I was able to create 102 distinct dataframes (DFs1, DFs2, DFs3, etc) using the assign() in a loop.
Now, I would like to perform the following transformation for each one of these dataframes: df1=DFs1[1,] df1=df1[,1:3] names(df1)=names(DFs1[c(1,4,5)]) df1=rbind(df1,DFs1[c(1,4,5)]) names(df1)=c("UID","Date","Location") something like this: for (i in 1 : nrow(unique)){ dfi=DFsi[1,] dfi=dfi[,1:3] names(dfi)=names(DFsi[c(1,4,5)]) dfi=rbind(dfi,DFsi[c(1,4,5)]) names(dfi)=c("UID","Date","Location") } I thought it could be straightforward but has proven the opposite Many thanks Laura [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org 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.
