add.extension: Associate a reader function with an extension.

.add.extensionR Documentation

Associate a reader function with an extension.

Description

This function will associate an extension with a custom reader function.

Usage

.add.extension(extension, reader)

Arguments

extension

The extension of the new data file.

reader

The function to use when reading the data file. It should accept three arguments: data.file, filename and variable.name (in that order). The function should read the contents of the file filename, and save it into the workspace under the name variable.name. The data.file argument is just a relative file name and can be ignored.

Value

No value is returned; this function is called for its side effects.

Warning

This interface should not be considered as stable and is likely to be replaced by a different mechanism in a forthcoming version of this package.
