Hay aristas múltiples, eso es por la preparación de los datos, es que separe por componentes, no me refiero al término componente estadístico, sino a descomposición de algo en los componentes que lo construyen, algunos son comunes y otros no, cuándo son comunes hay una relación en la red.

Buenos días,
Como resultado final de unos análisis espaciales que hago, genero unos
mapas y gráficos.
He creado una ficha como esta a mano:

¿Sería posible generar algo similar con R?
Por ahora lo que he encontrado sería escribir el html línea a

Estimados
Tengo un problema, creo que sencillo, pero hay algo que hice mal, coloco el código, básicamente desde igraph se realiza un análisis, y se me ocurre tener un data.frame para ordenar los resultados, pero justo en ese punto aparece un problema.
¿Alguna sugerencia?

Hola a todos:
Apliqué el método, pero me salió lo siguiente;

and then run the unit tests without further editing the code, I get
the following error:

Undefined method `register'' for REXML::Encoding:Module
Has anyone seen the below error before?
It appears to only occur when Puppet runs automatically (i.e. a "puppetd
--test" doesn''t cause it). I have recently installed new Ruby rpms on
the server and I''m guessing that I may have left out something when I
built the RPMS (based on FC7 SRPM).
