[R] Incorrect Summarization after As.numeric

[SHIVI BHATIA]

Dear Team,

 

I am working on aggregate function in R & have used the below code:

 

aggregate(a1$Final,list(Year=a1$Year),sum)

 

initially a1$Final was factor hence I used a1$Final= as.numeric(a1$Final) to
convert this into numeric. After conversion it shows the output but the
summarization from the aggregate is incorrect. This I have reconciled with
the excel pivot. 

 

Could you please suggest where could be the issue?

 

Thanks, Shivi
