actually i've tested this (it don't works but seems to be correct for me...):
My first try (i was trying to overwrite the table on the overlap):
tab[(no[off_set[i-1]+1]+(no[off_set[i]+1]-no[off_set[i-1]+1])):length(TotalFillTimeHours),1:length(tab)]<-tab[(no[off_set[i-1]+1]+(no[off_set[i]+1]-no[off_set[i-1]+1])):length(TotalFillTimeHours),1:length(tab)];
My second idea was to make 2 tab without the overlap, then put them together:
tab_tmp<-tab[1:(no...

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<-c(tab_tmp,tab_tmp1);
attach(tab);
Here is the output:
