I have data that looks like this: start end value 1 4 2 5 8 1 9 10 0
I want to transform the data so that it becomes: startend value 1 2 2 2 3 2 4 2 5 1 6 1 7 1 8 1 9 0 10 0 ---- I've written a for loop that can do the transformation BUT I need to do this on very large datasets (millions of rows). Does anyone know of an R package that has a function that can do this transformation? Any help is much appreciated!
