[R] a question about gradient in optim

Hi, I am using optim to estimate the parameters of a smooth transition autoregressive model. I wrote a function to return the gradient for each observation. So, for k parameters and n observations my function returns a (n x k) matrix. The gr argument of optim expects a (k x 1) vector. Now,
