What is a .RDATA file?
An .RDATA file is a special type of file that is created by a program called R. R is a software used for doing complex math calculations and creating graphs, and it is made by a group called The R Project for Statistical Computing. When you are working in R, you can create different things like functions (which are like mini-programs that do specific tasks) and values (which are numbers or data you're working with). All of these things you create during your work session can be saved together in an .RDATA file. This is really useful because it means you can save your work and come back to it later, adding more data or making changes without starting from scratch.
To open an .RDATA file, you can use R itself or a related program called RStudio, which is designed to make working with R easier. Another program that can open these files is Safe Software FME Desktop, but R and RStudio are the main ones people use.
For example, if you were working with a list of numbers in R, like 1, 2, 3, 4, 5, you could save this list in your workspace file (.RDATA file). But, it's important to know that when you open this file again in R, it won't automatically show you all the things you saved last time. To see them, you have to type in a special command like ls or objects, which tells R to list out everything that's saved in your file. RStudio makes this a bit easier because it has a special area on the screen that shows you all your saved items without needing to type in a command.
So, in simple terms, an .RDATA file is like a save file for your R projects, holding all the important work you've done so you can pick up right where you left off.
