make.clem {LoopAnalyst} | R Documentation |
Validates a community matrix and computes its associated change in life expectancy matrix.
make.clem(CM, status=FALSE)
CM |
A valid community matrix. |
status |
Switches on an element-by-element progress indicator when set to TRUE . Set to FALSE by default. |
The supplied matrix is validated as a community matrix, and a table of predicted changes in life expectancy (i.e. the inverse of turnover) given a press perturbation is computed. Diagonal elements can differ for births and deaths, and these predictions, in that order, are separated by a comma.
A change in life expectancy matrix
