constrOptim does ineq, not eq, but who do ?
...rain (all solutions sum to 1), thus I tried to fool constrOptim using: x[1] + 0 + ... + 0 >= 0 ... 0 + 0 + ... + x[n] >= 0 x[1] + x[2] + ... + x[n] >= 1 -x[1] - x[2] - ... - x[n] >= -1 in minimization: min( dist(A*x - b) ) But, since the initial guess x0 must be in the fasiable region and NOT in the boundaries (due to trick I only have boundary), this trick doens't work out. If constrOptim doesn't make subject to equalities, what function could do this optimization ? any ideia ? I look for something similar to MATLAB's lsqlin function: http://web.media.mit.e...
