Why convert DTA to RDATA?
.RData is R's native binary format understood by almost nothing outside R. Converting from .dta to .RData is useful when your analysis workflow lives in R - it avoids re-reading the .dta on every session and lets you bundle multiple cleaned R objects in a single file alongside the raw dataset.
How to convert DTA to RDATA
R + haven OPEN-SOURCE
Install haven (install.packages('haven')), run df <- read_dta('file.dta'), then save(df, file = 'output.RData'); in RStudio you can inspect the data frame in the Environment pane before saving.
About these formats
.DTA
Stata Data File
A DTA file is almost always a Stata dataset - the native binary format of the StataCorp Stata statistics package. You do not need a paid Stata licence to open one: PondPilot opens it free…

.RDATA
R Workspace / Saved Objects File
An RDATA file is a binary snapshot of one or more R objects - a saved R workspace created by R's save() function. Open it in R or RStudio with load("file.RData"), which restores all objects…

- Variable and value labels are kept as R attributes; call
as_factor(df)before saving if you need plain R factors instead. .RDatafromsave()can hold multiple named R objects;.rdsfromsaveRDS()holds exactly one - for a single dataset,.rdsis often cleaner..RDatais not portable outside R; if you need to share data beyond R users, export to CSV or XLSX instead.
Frequently asked questions
Do I need a Stata licence to do this conversion?
.dta files directly without Stata installed.What is the difference between `.RData` and `.rds`?
.RData from save() can hold multiple objects and restores them by their original names; .rds from saveRDS() holds one object, which you name when loading with readRDS().
