ascii: Export R objects to several markup languages

Description

Function converting an R object to an ascii object, which can then be printed with asciidoc, txt2tags, sphinx or org syntax.

Usage

## S3 method for class 'default':
ascii(x, 
    include.rownames = TRUE, include.colnames = TRUE,
    rownames = NULL, colnames = NULL, 
    format = "f", digits = 2, decimal.mark = ".", na.print = "", 
    caption = "", caption.level = "", width = 0, frame = "",
    grid = "", valign = "", header = TRUE, footer = FALSE,
    align = "", col.width = 1, style = "", cgroup = NULL,
    n.cgroup = NULL, calign = "", cvalign = "", cstyle = "",
    rgroup = NULL, n.rgroup = NULL, ralign = "", rvalign = "",
    rstyle = "", \dots)
  ## S3 method for class 'ftable':
ascii(x, digits = getOption("digits"), header = TRUE, ...)
  ## S3 method for class 'describe':
ascii(x, condense = TRUE, \dots)
  ## S3 method for class 'summary.table':
ascii(x, caption = "", caption.level = "", list.type = "bullet", \dots)
  ## S3 method for class 'list':
ascii(x, caption = "", caption.level = "", list.type = "bullet", \dots)
  ## S3 method for class 'sessionInfo':
ascii(x, locale = TRUE, ...)
  ## S3 method for class 'smooth.spline':
ascii(x, caption = "", caption.level = "", list.type = "bullet", \dots)

Arguments

An R object of class found among methods(ascii).

include.rownames

logical. If TRUE the rows names are printed. Default value depends of class of x.

include.colnames

logical. If TRUE the columns names are printed. Default value depends of class of x.

rownames

Character vector (replicated or truncated as necessary) indicating rownames of the corresponding rows. If NULL (default) the row names are not modified

colnames

Character vector (replicated or truncated as necessary) indicating colnames of the corresponding columns. If NULL (default) the column names are not modified

format

Character vector of length equal to the number of columns of the resulting table (otherwise it will be replicated or truncated as necessary) indicating the format for the corresponding columns. These values

digits

Numeric vector of length equal to the number of columns of the resulting table (otherwise it will be replicated or truncated as necessary) indicating the number of digits to display in the corresponding columns.

decimal.mark

The character to be used to indicate the numeric decimal point. Default is ".".

na.print

The character string specifying how NA should be formatted specially. Default is "".

caption

Character vector of length 1 containing the table's caption or title. Set to "" to suppress the caption. Default value is "".

caption.level

Character or numeric vector of length 1 containing the caption's level. Can take the following values: 0 to 5, "." (block titles in asciidoc markup), "s" (s

width

Numeric vector of length one containing the table width relative to the available width (expressed as a percentage value, 1...99). Default is 0 (all available width).

frame

Character vector of length one. Defines the table border, and can take the following values: "topbot" (top and bottom), "all" (all sides), "none" and "sides" (left and rig

grid

Character vector of length one. Defines which ruler lines are drawn between table rows and columns, and can take the following values: "all", "rows", "cols" and "none". Defa

valign

Character vector of length one indicating vertical alignment of all cells in table. Can take the following values: "top", "bottom" and "middle". Default is "".

header

logical. If TRUE the first line of the table is emphasized. The default value depends of class of x.

footer

logical. If TRUE the last line of the table is emphasized. The default value depends of class of x.

align

Character vector of length one indicating the alignment of the corresponding columns. Can be composed with "r" (right), "l" (left) and "c" (center). Default value is "".

col.width

Numeric vector of length equal to the number of columns of the resulting table (otherwise it will be replicated or truncated as necessary) indicating width of the corresponding columns (integer proportional values).

style

Character vector of length one indicating the style of the corresponding columns. Can be composed with "d" (default), "e" (emphasis), "m" (monospaced), "a" (cells can cont

cgroup

Character vector defining major column headings. The default is to have none (NULL).

n.cgroup

A numeric vector containing the number of columns for which each element in cgroup is a heading. For example, specify cgroup=c("Major 1","Major 2"), n.cgroup=c(3,3) if

"Major

calign

Character vector of length one defining alignment of major column headings.

cvalign

Character vector of length one defining vertical alignment of major column headings.

cstyle

Character vector of length one indicating the style of major column headings

rgroup

Character vector defining major row headings. The default is to have none (NULL).

n.rgroup

A numeric vector containing the number of rows for which each element in rgroup is a heading. Column names count in the row numbers if include.colnames = TRUE.

ralign

Character vector of length one defining alignment of major row headings.

rvalign

Character vector of length one defining vertical alignment of major row headings.

rstyle

Character vector of length one indicating the style of major row headings

list.type

Character vector of length one indicating the list type ("bullet", "number", "label" or "none"). If "label", names(list) is use

condense

default is TRUE to condense the output with regard to the 5 lowest and highest values and the frequency table (describe() in package Hmisc).

locale

default is TRUE to show locale information (sessionInfo()).

...

Additional arguments. (Currently ignored.)

Value

This function returns an object of class c("ascii","proto","environment").

Details

The nature of the output generated depends on the class of x. For example, summary.table objects produce a bulleted list while data.frame objects produce a table of the entire data.frame.

Sometimes, arguments are not active, depending of the features implemented in the markup language generated. All arguments are active when asciidoc syntax is produced.

The available method functions for ascii are given by methods(ascii). Users can extend the list of available classes by writing methods for the generic function ascii. All method functions should return an object of class c("ascii","proto","environment").

Examples

Run this code

data(esoph)
ascii(esoph[1:10,])
tab <- table(esoph$agegp, esoph$alcgp)
ascii(tab)
print(ascii(tab), type = "t2t")
print(ascii(tab), type = "sphinx")
print(ascii(tab), type = "org")
ascii(summary(tab))
