 El paquete **knitr** se diseñó para dar al usuario acceso a todas las partes del proceso de lidiar con un documento de programación literaria, de forma que no haya necesidad de modificar cualquiera de los componentes centrales si quiere mayor libertad. He estudiado el código fuente de **pgfSweave** y **cacheSweave** un par de veces, y frecuentemente me siento incómodo con la gran cantidad de código copiado del R oficial, especialmente cuando R tiene una nueva versión liberada (empezaré a preocuparme si los paquetes adicionales todavía están actualizados respecto al Sweave ocifial).
