I am trying to code the following excel formula in R. a b c Result Formula 1 10 0.1 #N/A IF(B2<20,NA(),C2+IF(ISERROR(D1),0,D1)) 2 20 0.2 0.2 IF(B3<20,NA(),C3+IF(ISERROR(D2),0,D2)) 3 30 0.3 0.5 IF(B4<20,NA(),C4+IF(ISERROR(D3),0,D3)) 4 40 0.4 0.9 IF(B5<20,NA(),C5+IF(ISERROR(D4),0,D4)) 5 50 0.5 1.4 IF(B6<20,NA(),C6+IF(ISERROR(D5),0,D5)) 6 60 0.6 2 IF(B7<20,NA(),C7+IF(ISERROR(D6),0,D6)) 7 70 0.7 2.7 IF(B8<20,NA(),C8+IF(ISERROR(D7),0,D7)) 8 80 0.8 3.5 IF(B9<20,NA(),C9+IF(ISERROR(D8),0,D8)) 9 90 0.9 4.4 IF(B10<20,NA(),C10+IF(ISERROR(D9),0,D9)) 10 100 1 5.4 IF(B11<20,NA(),C11+IF(ISERROR(D10),0,D10))
The variable "Result" is obtained using the excel formula shown next to it. Column D contains the Result. dataFrame <- data.frame(a = seq(1:10),b = seq(10,100,by = 10),c = seq(0.1,1,by = 0.1)) Can someone please help me as how to calculate the sequential sum in R given by the excel formula?? Thank you.
