Hyper Data Frame

Create a hyperframe: a two-dimensional array in which each column consists of values of the same atomic type (like the columns of a data frame) or objects of the same class.

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 atomic 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.


  • An object of class "hyperframe".

Methods for Hyperframes

There are methods for print, plot, summary, with, split, [, [<,$, $<-, names, as.data.frame as.list, cbind and rbind for the class of hyperframes. There is also is.hyperframe and as.hyperframe.

# equivalent to a data frame

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

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

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

  lambda <- runif(4, min=50, max=100)
  X <- lapply(as.list(lambda), function(x) { rpoispp(x) })
  h <- hyperframe(lambda=lambda, X=X)

  h$lambda2 <- lambda^2
  h[, "lambda3"] <- lambda^3
  h[, "Y"] <- X
