as.integer.hi: Hybrid Index, coercing from

Description

Functions that (back-)convert an hi object to the respective subscripting information.

Usage

# S3 method for hi
as.which(x, …)
# S3 method for hi
as.bitwhich(x, …)
# S3 method for hi
as.bit(x, …)
# S3 method for hi
as.integer(x, vw.convert = TRUE, …)
# S3 method for hi
as.logical(x, maxindex = NULL, …)
# S3 method for hi
as.character(x, names, vw.convert = TRUE, …)
# S3 method for hi
as.matrix(x, dim = x$dim, dimorder = x$dimorder
, vw = x$vw, symmetric = x$symmetric, fixdiag = x$fixdiag, …)

Arguments

x

an object of class hi

maxindex

the length of the subscripted object (needed for logical output)

names

the names vector of the subscripted object

dim

the dim of the subscripted object

dimorder

the dimorder of the subscripted object

vw

the virtual window vw of the subscripted object

vw.convert

vw.convert

symmetric

TRUE if the subscripted matrix is symmetric

fixdiag

TRUE if the subscripted matrix has fixdiag

…

further arguments passed

Value

as.integer.hi returns an integer vector, see as.hi.integer. as.logical.hi returns an logical vector, see as.hi.logical. as.character.hi returns a character vector, see as.hi.character. as.matrix.hi returns a matrix index, see as.hi.matrix.

Examples

# NOT RUN {
  x <- 1:6
  names(x) <- letters[1:6]
  as.integer(as.hi(c(1:3)))
  as.logical(as.hi(c(TRUE,TRUE,TRUE,FALSE,FALSE,FALSE)))
  as.character(as.hi(letters[1:3], names=names(x)), names=names(x))
  x <- matrix(1:12, 6)
  as.matrix(as.hi(rbind(c(1,1), c(1,2), c(2,1)), dim=dim(x)), dim=dim(x))
