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 <- combn(c(coeff1,coeff2,...,coeff19),function(x) matrix(x,6,6)) but i think that R doesn't recognize that these are not scalars. In fact the error is: Errore in matrix(r, nrow = len.r, ncol = count) : invalid 'ncol' value (too large or NA) Inoltre: Warning message: In combn(c(coeff1, coeff2, coeff3, coeff4, coeff5, coeff6, coeff7, : si รจ prodotto un NA per coercizione Some ideas?
