Retrieve the values of the primal variables from a successfully solved lpSolve linear program model object.
1 | get.primal.solution(lprec, orig = FALSE)
|
lprec |
an lpSolve linear program model object. |
orig |
a logical value. When presolve is active, the size of the lp may decrease during solve. By default, the answer to this reduced problem is returned. Set this argument to |
a numeric vector containing the values of the primal variables. If an error occurs (for instance lprec
has not been successfully solved) a NULL
value is returned.
