Hi, I found the reason. By default it puts a condition for x >= 0. Is there a way to get rid of this condition? Medha On Fri, Oct 23, 2009 at 2:34 PM, Medha Atre wrote: > Hi, > > I am using R in one of my courses. I am trying to use R's linprog > package to solve to formulate 2-class classific

Hi, I am using R in one of my courses. I am trying to use R's linprog package to solve to formulate 2-class classification problem as Linear programming problem. For my formulation, I need to set to "cvec" to all 0s. I know the points are linearly separable so an optimal solution "x" does exist,
