Hi all;
I am quite new in R. I have tried write a loop to sum up a column and cut off
when summation reach certain point. Here are a small example and my R codes.
Your helps are truly appreciated,
Oslo
I would like to sum up the B$a column and cut off at 0.7 for the each row of
intervals giving in file=A.For example the interval at the first row in A$posA
and A$posB is 1 and 9. So, I need adding up the B$a and cut off B$a>.7 from the
1 to 9 in B$pos. And then I need to the same using the intervals in the second,
third..... rows in A. Obviously my loop is wrong and does not work properly.
Please help for my this first experience. Thanks.
Here are my codes
#sorting B$possort=B[order(B$pos),]
#Running loop
for(i in 1:nrow(A)) {if(sum(B[a$B, i:A[1:2])>0.7) {print(A[1:i,]) } }
