as-array

Converting Data Frames into Arrays

Description

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 signature '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

Examples

BerkeleyAdmissions <- to.data.frame(UCBAdmissions)
BerkeleyAdmissions
as.array(BerkeleyAdmissions,data.name="Admit")
try(as.array(BerkeleyAdmissions[-1,],data.name="Admit"))
