get.branch.mode {lpSolveAPI} | R Documentation |
Retrieve the branch mode for one or more decision variables from an lpSolve linear program model object.
get.branch.mode(lprec, columns = 1:n, as.char = TRUE)
lprec |
an lpSolve linear program model object. |
columns |
a numeric vector of unique values from the set {1, ..., n} (where n is the number of decision variables in lprec ) specifying for which decision variables the branch modes should be retrieved. If NULL branch modes are retrieved for all the decision variables. |
as.char |
a logical value. If TRUE the branch mode is returned as a character string, otherwise the integer code used directly in lpSolve is returned. |
either a character vector or an integer vector containing the branch modes for the decision variables specified in columns
. The possibilities are: 0 = "ceiling"
, 1 = "floor"
and 2 = "auto"
.
