I have data containing columns biweek
and Total
, I want to get cumulative sum on biweek
basis. My data is like:
biweek Total
0 3060.913
1 4394.163
2 3413.748
3 2917.548
4 3442.055
5 3348.398
6 1771.722
and I want to get output like :
biweek Total
0 3060.913
1 7455.076
2 10868.824
3 13786.372
4 17228.427
5 20576.825
6 22348.547
So it there a possible way to achieve it?
# replace the second column for the cumsum of the initial second column
data[, 2] <- cumsum(data[, 2])
