hi all Here is a small part of my code:
tab_tmp<-tab[1:(no[off_set[i-1]+1]+(no[off_set[i]+1]-no[off_set[i-1]+1])),length(tab)]; tab_tmp1<-tab[(no[off_set[i-1]+1]+(no[off_set[i]+1]-no[off_set[i-1]+1])):length(TotalFillTimeHours),length(tab)]; tab<-c(tab_tmp,tab_tmp1); attach(tab); Here is the output: Error in attach(tab) : attach only works for lists and data frames Execution halted How do i concatenate them in order to keep the data frame structure? thks for your help guillaume ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
