Hello all! Maybe it's a newbie question(in fact I _am_, a newbie), but I hope you'll find the solution. I have an equation system which has k equation and n variables (k<n). I would like to obtain a description of the solutions (which can be the equation of lines or a plane, or everything else) with the lesser degree of freedom, obviously using R. In other words, I would like to

Hello! I've a problem with the combn function and a set of vector. I would like to make a simple combination where, instead of scalars, i would like to combine vector, in order to form matrixes. In other words, i have nineteen 6-items vectors (for example coef1-coef19), that i would like to combine in n!/k!(n-k)! 6x6 matrixes. I tried with a code like this mma <-
