[R] How to compute the minimal distanct between a point and curve in N-dim space

Dear All, In the N-dimensional space, give a data point A and a curve f, how to write the explicit expression for calculating the minimal distance between A and f? Or have to use some nonlinear optimization method to calcualte it? Thanks for your point. Fred [[alternative HTML
