Description

Convert a data.frame into a data.list

Usage

Arguments

The data.frame to be converted.

Details

A data.list is simply a list of vectors and data.frames. For the use in the onlineforecast package the following format must be kept:

- t: A vector of time.

- vectors with same length as t: Holds observations and values synced to time t.

- data.frames with number of rows as time t: Holds forecasts in each column named by kxx where xx is the horizon, e.g. k0 is synced as observations, and k1 is one-step ahead.

The convention is that columns with forecasts are postfixed with .kxx where xx is the horizon. See the examples.

Value

a value of class data.list

a data.list

# Convert a dataframe with time and two observed variables
X <- data.frame(t=1:10, x=1:10, y=1:10)
as.data.list(X)

# Convert a dataframe with time, forecast and an observed variable
X <- data.frame(t=1:10, x.k1=1:10, x.k2=10:1, yobs=1:10, y.k1=1:10, y.k2=1:10)
as.data.list(X)

# Can be converted back and forth
X
as.data.frame(as.data.list(X))
