lprec |
an lpSolve linear program model object. |
x |
a numeric vector containing the elements (only the nonzero elements if the |
indices |
optional for sparse |
This function adds an additional column to an lpSolve linear program model object. If multiple columns are to be added, performance can be improved by calling resize.lp
