hyperframe: Hyper Data Frame

Description

Create a two-dimensional array in which each column consists of values of one type (as in a data frame) or consists of objects of one class.

Usage

hyperframe(...,
             row.names=NULL, check.rows=FALSE, check.names=TRUE,
             stringsAsFactors=default.stringsAsFactors())

Arguments

...

Arguments of the form value or tag=value. Each value is either an atomic vector, or a list of objects of the same class, or a single atomic value, or a single object. Each value will become a

row.names,check.rows,check.names,stringsAsFactors

Arguments passed to data.frame controlling the names of the rows, whether to check that rows are consistent, whether to check validity of the column names, and whether to convert character co

Value

An object of class "hyperframe". There are methods for print, plot, summary, [, $, $<-, names, as.data.frame and as.list for this class. There is also a cbind.hyperframe.

Details

A hyperframe is like a data frame, except that its entries can be objects of any kind.

A hyperframe is a two-dimensional array in which each column consists of values of one type (as in a data frame) or consists of objects of one class.

The arguments ... are any number of arguments of the form value or tag=value. Each value will become a column of the array. The tag determines the name of the column.

Each value can be either

an atomic vector or factor (i.e. numeric vector, integer vector, character vector, logical vector, complex vector or factor)
a list of objects which are all of the same class
one atomic value, which will be replicated to make an atomic vector or factor
one object, which will be replicated to make a list of objects.

All columns (vectors, factors and lists) must be of the same length, if their length is greater than 1.

Examples

Run this code

# equivalent to a data frame
  hyperframe(X=1:10, Y=3)

 # list of functions
  hyperframe(f=list(sin, cos, tan))

 # table of functions and matching expressions
  hyperframe(f=list(sin, cos, tan),
             e=list(expression(sin(x)), expression(cos(x)), expression(tan(x))))

  hyperframe(X=1:10, Y=letters[1:10], Z=factor(letters[1:10]),
    stringsAsFactors=FALSE)

  lambda <- runif(10, min=50, max=100)
  X <- lapply(as.list(lambda), function(x) { rpoispp(x) })
  hyperframe(lambda=lambda, X=X)
