Save key as file after deducing type from suffix

Description

This is specialized to saving of key objects, it is not a general purpose function for saving things. It scans the suffix of the file name and then does the right thing.

Usage

keySave(obj, file, na_ = ".", varlab)

Arguments

obj	a variable key object
file	file name. must end in "csv", "xlsx" or "rds"
na_	Value to insert to represent a missing score. Default ".".
varlab	FALSE or TRUE. Default is FALSE, no new labels will be created. If a key object has a varlab already, it is saved with the key, always. This parameter controls whether a new varlab template should be created when the object is saved. If TRUE and obj has no varlab attribute, a new varlab template is created by the varlabTemplate function. If TRUE and a varlab attribute currently exists, but some variables are missing labels, then varlabTemplate is called to fill in new variable labels.

Details

In updates 2017-09, a varlab element was introduced. The varlab attribute of the object is saved. The files created incorporate the variable labels object in different ways. 1) XLSX: variable labels a worksheet named "varlab" 2) CSV: variable labels saved in a separate file suffixed "-varlab.csv". 3) RDS: varlab is an attribute of the key object.

Value

NULL if no file is created. Otherwise, a key object with an attribute varlab is returned.
