set_bounds | R Documentation |
Change the lower and upper bounds of a named variable, indexed variable or a group of variables.
set_bounds(.model, .variable, ..., lb = NULL, ub = NULL)
set_bounds_(.model, .variable, ..., lb = NULL, ub = NULL, .dots)
.model |
the model |
.variable |
the variable name/definition or a linear constraint |
... |
quantifiers for the indexed variable |
lb |
the lower bound of the variable. |
ub |
the upper bound of the variable For |
.dots |
Used to work around non-standard evaluation. |
