[R-es] problema al instalar rPython

[Javier Martínez-López]

Hola,

necesito combinar código de R y de Python y quiero probar la librería
"rPython" para poder intercambiar variables creadas en los dos
entornos, pero me da el siguiente error que no comprendo al intentar
instalar la librería (ver abajo). Uso una versión local de Python
llamada Anaconda en CentOS (Redhat) porque no tengo permisos de
administración. No sé si ese es el problema! Muchas gracias y saludos,
Javier
