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 = " 

",
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

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).

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)
