Com fins ilustrativos e exploratório, tenho pontos correspondentes a dois tratamentos A e B espacialmente distribuídos no campo, estou delimitando o limite (zona de influência) de cada um como uma elipse, através da função ellipsoidhull() do pacote cluster conforme CRM abaixo. Gostaria de saber se alguém familiarizado com a função poderia me dizer como faço para extrair os raios e as áreas das elipses EpointsA e EpointsB?<br>
