movement_matrix is not a full matrix

[Spatial-R]

Hello, thanks for your nice package. When using the package to predict the human movement, I came across a question and hope you can give me some advices.

For each location, we have obtained the top 100 human flow among locations, rather than the human flow among all the regions. Therefore, the movement matrix is not a full matrix, there was some missing value in the matrix. For instance, we gathered the population flow between A and B as well as B and C, but we don't know the exact human flow between A and C. If we remove the location with the missing value, the number of regions remaining in the movement matrix is quite small. In this situation, how can I use the movement package to predict the human flow between A and C?
