    dimnames(x) <- value

### Arguments

`x` | an lpSolve linear program model object.
`value` | a list containing two character vectors of lengths `m` and `n` specifying the row names and the column names for the lpSolve linear program model object. The number of constraints in `x` is denoted by `m` and the number of decision variables by `n`.
