Ok I need help with splitting vector slot data.

[Melicalol]

Suppose I have this vector it contains dates example

Vector.Dates [slot 1][slot 2] [slot 3] etc...

anyways slot 1 contains [ 05282013]
slot 2 contains [07032015]

I want to split the data it contains into 3 other locations How do I do that???

like vector.1[05][07]
vector.2 [28][03]
vector.3[2013][2015]

How do you only take partial data from a vector slot?

Thanks!, any help will be appreciated.
