how to create and manage a matrix with vector of different length
...s, maybe c(3,34,178,.....), means that the NO.34 county is the second closest the NO.3 county. We can call it DISTANCE matrix.
From DISTANCE matrix, I can get a matrix POP and matrix CASE into the corresponding cell of the DISTANCE matrix respectively, by "cumsum" command and get matrix CUMPOP and matrix CUMCASE, which can explained different size circle of different center, and we can call a function element-wise
The problem, I want to restrict the cumulative population of each circle within 50% of the total population, which will make every row-vector have different length. e.g. the...
