constraints
Is there a package in R that handles general linear (in-)equality + box
constrained optimization?
If it is not there, could anyone advise me which way to go?
And/or point me to packages that solve these problems partially?
best, ingmar

I need to plot an illustrative figure without ticks, x, y labels in R. I
