R version support

R evolves every year. Each update brings many bug fixes and performance improvements, but also sometimes changes the default value of some parameters (such as switching from stringsAsFactors = TRUE to FALSE in R 4.0.0).

While there is benefit in supporting older R versions, doing so adds maintenance burden, especially in a large ecosystem like easystats that contains 10 packages that are supposed to seamlessly work together. Therefore, easystats is supported (meaning each package is thoroughly tested) on the current R version, the future one (R-devel) and the previous five versions.

The current planned release schedule for large R updates is once a year in Spring. Accordingly, this table shows the corresponding latest R version and the oldest supported version:

Year Latest R version Oldest supported R version
2023 4.3 3.5
2024 4.4 3.6
2025 4.5 4.0
2026 4.6 4.1
2027 4.7 4.2
2028 4.8 4.3

(Of course, if the R release schedule changes or R releases a “5.0” version, the numbers in the table will change.)

Implications

The implications are simple:

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
