make.cem {LoopAnalyst} | R Documentation |
Validates and community matrix and computes its associated community effect matrix.
make.cem(CM, status=FALSE, out=FALSE)
CM |
A valid community matrix. |
status |
Switches on an element-by-element progress indicator when set to TRUE . Set to FALSE by default. |
out |
Switches on formatting of community effect matrix element output from "-1", "0", "1", "NA " to "-", "0", "+", and "?" respectively when set to TRUE . Set to FALSE by default. |
The supplied matrix is validated as a community matrix, and the community effect matrix (i.e. table of predictions) is computed. Ambiguous effects are represented by link{NA}
.
