After successfully implementing the classical portfolio optimization model, I am looking for an efficient way to draw the whole feasible investment area in R (in addition to the efficient investment frontier). My current approach is to generate random portfolio weights (uniformly distributed inside a simplex), check that constraints are held and plot them. However, the charts I get are very different to the ones that I have seen as output from other programs (. OptiFolio , ECVaR ). My results show a very small cloud of portfolios.
