RDATA File

What are RDATA files and how to open them

Are you having problems opening a RDATA file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your RDATA files.

What is a RDATA file?

A .RDATA file is a R Saved Work Space file.

A file with extension ".RData" is a saved workspace produced by the R statistical computing environment. When you're working interactively in R (or via RStudio) you create objects like data frames, functions, vectors, and other results. Saving the workspace snapshot stores all of those objects in one file so you can quit R and later restore exactly what you had, without re-running all your work.

The R function that makes this file is save() (or save.image() for the entire workspace). The file is later loaded back into R using load(). It can also be used to share an R workspace with others so that they can pick up work, explore your variables, or reproduce your data analysis as it was when it was saved.

An .RData file typically begins with a signature "RDX2" at byte offset zero when saved in the default binary (XDR) format. It also includes encoded structures for named objects ("NAMES"), classes ("CLASS"), tabular data ("DATA.FRAME"), and similarly typed components.
