Set Column
Description
Set a column in an lpSolve linear program model object.
Usage
set.column(lprec, column, x, indices)
Arguments
lprec |
an lpSolve linear program model object.
|
column |
a single numeric value from the set {1, ..., n} specifying which column to set.
|
x |
a numeric vector containing the elements (only the nonzero elements if indices is also given) to be used in the added column. The length of x must be equal to the number of constraints in lprec unless indices is provided.
|
indices |
optional for sparse x . A numeric vector the same length as x of unique values from the set {0, ..., m} where m is the number of constraints in lprec ; x[i] is set in constraint indices[i] in the specified column. The coefficients for the constraints not in indices are set to zero. In particular, index 0 is the objective function coefficient in the specified column and is set to zero by default. This argument should be omitted when length(x) == m .
|
Value
a NULL
value is invisibly returned.
