s2pre: Writes out data.frame or matrix to a prelude-file.

Description

Data.frame or matrix object is written to a prelude-file, that inherits names/dimnames attributes from the object.

Usage

s2pre(data, file = "splus.pre", na.replace = "")

Arguments

data

Data.frame or matrix object.

file

Name of the output file ("Splus.pre" by default).

na.replace

A character to replace NA with in the output file ("" by default).

Value

A prelude-file representation of the data-object is written to a file.

Side Effects

No warning is given if the filename "file" already exists -- it is simply over-written.

See Also

cat, write.
