La idea es empezar a implementar Data Mining con rattle, el tema es que
queda freezado el rstudio al intentar leerlo.

Por lo que leí existe un paquete RevoScaleR pero es propietario y no tengo

Un abrazo

R 64-bit and Revolution
Dear users,
The company where I work is considering getting a license for Revolution

Thanks in advance.
