Yes, they were replaced by charisma.
Originally, they were actually separate skills.
I think they still are...sort-of....in dialogue you can still go for all three and each has a different value for me. I'm guessing each is calculated based on your character's charisma, the NPC's charisma and their personality(ie not all respond the same to threats)....not really sure but they all seem to still be in even if we can only put points in the overall charisma.
