R Documentation

Description

This function produces a data.frame of all data files in the project, with meta data on if and how the file will be loaded by load.project.

Usage

Details

The returned data.frame contains the following variables, with one observation per file in data/:

`filename`	Character variable containing the filename relative to `data/` directory.
`varname`	Character variable containing the name of the variable into which the file will be imported. *
`is_ignored`	Logical variable that indicates whether the file. is ignored through the `data_ignore` option in the configuration
`is_directory`	Logical variable that indicates whether the file is a directory.
`is_cached`	Logical variable that indicates whether the file is already available in the `cache/` directory.
`cached_only`	Logical variable that indicates whether the variable is only available in the `cache/` directory. This occurs when calling the cache function with a code fragment in a munge script.
`reader`	Character variable containing the name of the reader function that will be used to load the data. Contains a `character(0)` if no suitable reader was found.

* Note that some readers return more than one variable, usually with the listed variable name as prefix. This is true for for example the xls.reader and xlsx.reader.
