I have a vector of values, in which I would like to recursively repeat each element a variable amount of N times according to another vector, using R.
I know how to repeat each element exactly the same N times with repeat(x, each=N), but I cannot figure it out how to generate a variable number of repetitions.
An example:
Vector of values
0.5, 0.3, 0.2, 0.3, 0.1, 0.5, 0.1, 0.7 ....
Vector of repetition
2, 2, 3, 4, 3, 1, 5, 4 ....
Expected result
0.5, 0.5, 0.3, 0.3, 0.2, 0.2, 0.2, 0.3, 0.3, 0.3, 0.3, 0.1, 0.1, 0.1, 0.5, 0.1, 0.1, 0.1, 0.1, 0.1, 0.7, 0.7, 0.7, 0.7 ....
I guess some kind of apply function family could work but cannot get the proper code to do it...
Could anyone help?
Many thanks
