[R] align

[Omar Lakkis]

Is there a function in R that is similar to Splus's align?

The idea is, if I have a data.frame, or an its object that is like this:

2002-01-03   5
2002-01-04   NA
2002-01-05   7
2002-01-06   NA

I want to align it by the last value to this:

2002-01-03   5
2002-01-04   5
2002-01-05   7
2002-01-06   7
