[R-es] Obtener una df a partir de una lista (o algo así)

Buenos días, estoy tratando de implementar el código que veis abajo, de la documentación del paquete xgboost. Me desconcierta que al cargar las bases de datos aparezcan como listas. Cuando la llama directamente al aplicar la función xgboost (data = train$data) me desconcierta todavía más. Entiendo

Re: [R] uint8

Hi Luca, The answer to your question depends on your application. What do you want to do with x3? Do you really need a native vector to represent x1 and x2? Or you just want an object that behaves like it is a joint of x1 and x2? I do not think you can have a native vector x3 without paying
