Hi everyone, I have some data in a matrix, and I want to shift it down by one row. The matrix in question has a date column. Does anyone know of a way to shift the data by one row, whilst preserving the date column in the matrix - i.e. shift the data and leave the date column in the current location?

Can you provide commented, minimal, self-contained, reproducible code. If you don't have code, at least provide a before/after version of the matrix that you would like. It is easy to use indexing to move stuff around, we just have to know what is it that you want to move.

If its a zoo or ts time series you can use the lag function.
