How could I choose subvector of a vctor. for example if  
v=c(1,2,5,0,1), how
could I chose the (1,2) or (1,2,5).

I didn't notice at first that you wanted the values 1,2,5 ...(thought  
you wanted the 1st 2nd and 5th (obviously not correct with only a 4  
element vector)... so your values would be accessed with

v[1:3]
