Set constraint types in an lpSolve linear program model object.
Usage
set.constr.type(lprec, types, constraints = 1:m)
Arguments
lprec
an lpSolve linear program model object.
types
either a numeric vector or a character vector containing elements from the set {1 = "<=", 2 = ">=", 3 = "="} specifying the types of constraints. Additionally, the contraint type can be set to free uinsg the code 0.
constraints
a numeric vector of unique values from the set {1, …, m} (where m is the number of constraints in lprec) specifying which constraints to set.
# NOT RUN {lps.model <- make.lp(4, 2)
x <- c(6,2,4,9)
set.column(lps.model, 2, x)
y <- c(3,1,5)
ind <- c(1,2,4)
set.column(lps.model, 1, y, ind)
set.constr.type(lps.model, rep("<=", 4))
