i have an xts object:
aaa bbb ccc ddd
2001-01-02 179.7061 239.11 1712.60 271.10
2001-01-03 181.1751 243.24 1689.10 267.15
2001-01-04 181.6126 242.09 1737.86 267.10
i simply want translate upward all the values
So values in first row are lost. All others traslate upward
In my example, xts object should become:
aaa bbb ccc ddd
2001-01-02 181.1751 243.24 1689.10 267.15
2001-01-03 181.6126 242.09 1737.86 267.10
2001-01-04 NA NA NA NA
Any idea how to do this upward translation?
thanks
