set.bounds {lpSolveAPI} | R Documentation |
Set bounds on the decision variables in an lpSolve linear program model object.
set.bounds(lprec, lower = NULL, upper = NULL, columns = 1:n)
lprec |
an lpSolve linear program model object. |
lower |
a numeric vector of lower bounds to be set on the decision variables specified in columns . If NULL the lower bounds are not changed. |
upper |
a numeric vector of upper bounds to be set on the decision variables specified in columns . If NULL the upper bounds are not changed. |
columns |
a numeric vector of values from the set {1, ..., n} specifying the columns to have their bounds set. If NULL all columns are set. |
a list of logical values indicating whether the bounds were successfully set.
