In HH: Statistical Analysis and Data Display: Heiberger and Holland

Generate the latex code for an "array" or "table" with 3, 4, or more dimensions.

Description

Generate the latex code for an "array" or "table" with 3, 4, or more dimensions.

Usage

## S3 method for class 'array'
latex(object, ...,
       var.sep = "}\\tabularnewline{\\bfseries ", value.sep = ": ",
       use.ndn = TRUE, cgroup = NULL,
       ## rgroup here captures and ignores any incoming rgroup argument
       rgroup = NULL, n.rgroup = NULL,
       title = first.word(deparse(substitute(object))),
       rowlabel=title,
            rsubgroup=NULL, n.rsubgroup=NULL)

## S3 method for class 'matrix'
latex(object, ...,
        use.ndn=TRUE, cgroup=NULL,
        title=first.word(deparse(substitute(object))),
        rowlabel=title)

## S3 method for class 'table'
latex(object, ...) ## prepend c("matrix", "array") to the
        ## class of the input object, and then call latex.default

Arguments

object	A c("matrix", "array") or "table" object.
...	Arguments forwarded to the "default" method for latex.
use.ndn	Logical. ndn is an abbreviation for "Names of DimNames". When TRUE (the default), the rowlabel, cgroup, and rgroup values will be taken from the names(dimnames(object)).
rgroup, n.rgroup	These are the standard arguments for latex. Incoming values for rgroup and n.rgroup are ignored by latex.array and replaced with values constructed from the names of the dimnames of the third and higher dimensions of the input array object. Each item in rgroup is assigned the appropriate combination of names(dimnames(object))[-(1:2)].
rsubgroup, n.rsubgroup	These are based on the standard arguments for latex. Incoming values for rsubgroup and n.rsubgroup are applied to the rows of each rgroup.
title, rowlabel, cgroup	These are the standard arguments for latex. When use.ndn is TRUE (the default), then rowlabel is assigned the names(dimnames(object))[1] and cgroup is assigned the names(dimnames(object))[2].
value.sep	When use.ndn is TRUE (the default), and length(dim(object)) >= 3 then this string is used in the constructed rgroup values to separate the factor name from the factor level of the specified dimension, for example ABC: 5.
var.sep	When use.ndn is TRUE (the default), and length(dim(object)) >= 4 then this string is used in the in the constructed rgroup values to separate the name and level of each dimension, for example ABC: 5 ; DEF: 6. The default value is exactly what Hmisc::latex needs in order to place two or more lines (one for each dimension) in boldface.

Details

latex.matrix calls latex.default directly. When use.ndn is TRUE (the default), rowlabel and cgroup are constructed from names(dimnames(object)) unless the user explicitly specified them.

latex.array appends all two-dimensional layers object[,, one, at, a, time] into a single long "matrix", ignores any incoming rgroup and n.rgroup (with a warning), and constructs rgroup and n.rgroup to label the layers. When use.ndn is TRUE (the default), rowlabel and cgroup are constructed from names(dimnames(object)) unless the user explicitly specified them.

latex.table prepends c("matrix", "array") to the class of the "table" object, then calls the generic "latex". This step is necessary because the survey package creates objects whose class includes the value "table" but not the values c("matrix", "array"). Should this object be sent directly to latex.default, it would cause on error for any table with dimension larger than two.

## This sets up the defaults for latex to write to a pdf file

## It is needed for R CMD check.
## It is recommended if you normally use pdflatex.
## If you want some other destination for latex, use a non-default argument.
