Write Data in StatDataML Format

Description

Write data in StatDataML format, either in a file or to standard output

Usage

writeSDML(x, file = "", textdata = NULL, dtd = NULL, sep = " &#x000A;&#x000D;",
na.string = "NA", null.string = "NULL", posinf.string = "+Inf",
neginf.string = "-Inf", nan.string = "NaN", true = "1", false = "0",
title = deparse(substitute(x)), source = "R", version = " ",
date = NULL, comment = " ", properties = NULL)

Arguments

`x`	a data object.
`file`	the name of the file to write to.
`textdata`	save array elements as `textdata` blocks instead of `data`? Numeric arrays are by default (`textdata=NULL`) saved in `textdata` blocks, character arrays in `data` blocks.
`dtd`	location of the StatDataML DTD.
`sep`	field separator for `textdata` blocks.
`na.string`	the string which should be interpreted as `NA` element.
`null.string`	the string which should be interpreted as NULL string.
`posinf.string`	the string which should be interpreted as `+Inf`.
`neginf.string`	the string which should be interpreted as `-Inf`.
`nan.string`	the string which should be interpreted as `NaN`.
`true, false`	the strings which should be interpreted as `TRUE`/`FALSE`.
`title`	the title of the data being saved (string).
`source`	the source of the data being saved (string).
`version`	the version of the data being saved (string).
`comment`	a free form commentary for the data being saved (string).
`date`	a free form date element, date() by default.
`properties`	an arbitrary list or array.

Details

info attributes of arrays are used for the info attributes of the e / ce / na tags in StatDataML. For further details on the StatDataML format see the proposal.

Examples

A <- matrix(1:16, ncol=4)
rownames(A) <- paste("row", 1:4, sep="")
colnames(A) <- paste("col", 1:4, sep="")

# export to temporary file
tmp_file1 = tempfile()
writeSDML(A, tmp_file1)

I <- letters[1:16]
attr(A, "info") <- I

# export to temporary file
tmp_file2 = tempfile()
writeSDML(A, tmp_file2, textdata = FALSE)

# cleanup
unlink(tmp_file1)
unlink(tmp_file2)
