How do SPSS, R compare side by side?
The table below compares SPSS, R across 11 procurement-relevant dimensions, from license / cost through data file interchange.
Side-by-side comparison
| Dimension | SPSS | R |
|---|---|---|
| License / cost | Commercial, per-seat or per-site subscription | Free, open source (GPL) |
| Interface | Menu-driven Data Editor, with optional syntax (.sps) | Code-only, typically via RStudio/Posit or a notebook environment |
| Programming required | No (optional for advanced/reproducible use) | Yes |
| Learning curve | Low for standard tests via menus | Higher up front; pays off with flexibility |
| Extensibility | IBM add-on modules (Complex Samples, Missing Values, Amos, etc.) | Tens of thousands of community CRAN/Bioconductor packages |
| Reproducibility by default | Possible via saved syntax, but not the default workflow | Built in -- every analysis is a script |
| Origin | 1968 (SPSS Inc.); acquired by IBM in 2009 | Early 1990s, University of Auckland (Ihaka & Gentleman) |
| Governing body | IBM (proprietary) | R Foundation for Statistical Computing |
| Common disciplines | Psychology, sociology, education, survey/market research, nursing | Biostatistics, epidemiology, ecology, bioinformatics, econometrics, data science |
| Version-control friendliness | Syntax files can be version-controlled, but often aren’t by default | Scripts version-control cleanly (Git) as standard practice |
| Data file interchange | .sav format; readable by R via haven/foreign packages | Reads/writes .sav via haven/foreign; native formats are plain text/RDS |
Common questions
Common questions about SPSS vs R
Can R do everything SPSS can do?
+
Essentially yes, and generally more -- every standard test SPSS offers has an R equivalent, plus methods SPSS doesn’t offer at all. The gap is ease of access for a non-programmer, not capability.
Can I import SPSS data files into R, or vice versa?
+
Yes. R packages such as haven and foreign read and write SPSS’s native .sav format directly, and IBM’s R Integration Plug-in lets SPSS syntax call R code.
Is SPSS being replaced by R in academic research?
+
Not uniformly. R adoption is growing where reproducibility expectations are rising, but SPSS remains deeply embedded in social-science training pipelines. The realistic pattern is a shift in the mix, not wholesale replacement.
Does using SPSS mean my analysis can’t be reproducible?
+
No, but it requires discipline: run everything from saved, shared .sps syntax files rather than raw menu clicks, and archive the syntax alongside the data and output.
Which is better for a systematic review or meta-analysis?
+
Most meta-analysis work today happens in R, largely because of purpose-built packages (such as metafor) and because the reproducible-script workflow fits the documentation standards evidence synthesis expects.
