<p style="margin-top:0; margin-bottom:0">Desconozco lo que estés haciendo pero en general, no es una buena práctica trabajar de eso modo a menos que sea para visualización en un documento. Lo recomendable es trabajar con la información como la tienes y no la
transformes de esa forma. Si aun así decides hacerlo prueba la función dcast del paquete data.table.</p>
