y que al hacer el plot(p) te da un grafico como este,
.
Como se puede observar tiende a ser una línea recta paro con bastantes oscilaciones, por lo que para que se vea bien como línea recta se me ha ocurrido encontrar todos los valores donde hay un máximo en las oscilaciones y guardar esos valores para al momento de graficarlos se vea como una línea recta. El problema es que no se me ocurre una manera de recuperar esos máximos. Si me pueden ayudar seria de maxima utilidad.

y que al hacer el plot(p) te da un grafico como este,
.Como se puede observar tiende a ser una línea recta paro con bastantes oscilaciones, por lo que para que se vea bien como línea recta se me ha ocurrido encontrar todos los valores donde hay un máximo en las oscilaciones y guardar esos valores para al momento de graficarlos se vea como una línea recta.
