Converting Data Frames into Arrays

The as.array for data frames takes all factors in a data frame and uses them to define the dimensions of the resulting array, and fills the array with the values of the remaining numeric variables.

Currently, the data frame must contain all combinations of factor levels.

Usage
# S4 method for data.frame
as.array(x,data.name=NULL,…)
Arguments
x

a data frame

data.name

a character string, giving the name attached to the dimension that corresponds to the numerical variables in the data frame (that is, the name attached to the corresponding element of the dimnames list).

other arguments, ignored.

Value

An array
