ReadData: Reads data from an RDS data file via a file open dialog.

In irwinsnet/FIRST_api_R: Tools to Download and Convert FIRST API Data to R Data Frames

Description

Displays the tcltk package's read file dialog. Once the user enters or selects a file name, ReadData() will read and return the value stored in the corresponding RDS data file. The dialog will initially display the current working directory (see getwd() and setwd()).

Usage

ReadData()

Details

ReadData uses the readRDS() function, from R's base package, to read R data. The data is stored in the RDS file as an unnamed object, so the user must assign the return value to a named variable.

Throws an error if the selected file does not end in "RDS" (case-insensitive). Prints a message if the user cancels the dialog without selecting a file.

Value

The R object stored in the RDS data file, or NA if the user cancels the dialog without selecting a file.
