Subject: concatenate data frame
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
