Hi,
The data is
x <- c(4,3,5);
I need to translate it to
y <- c(1,2,3,4,1,2,3,1,2,3,4,5);
i.e. for each number in x, we need to generate 1:x and put it in y.
The program need to evaluate this type of calculation for millions of times in
simulation. Is there any elegant way to make this happen without iteration?
Many thanks!!
Best,
Haoda
