Hi R-experts,

I have a data frame (A) , and a subset (B) of this data frame. I am trying to create a new data frame which gives me all the rows of B, plus the 5th next row(occuring in A). I have used the below code, but it gives me all 5 rows after the matching row. I only want the 5th.

FiveDaysLater <- A[c(sapply(match(rownames(B),rownames(A)), seq, length=6))),]

Any guidance much appreciated,
Thankyou.
