# R, MRAN, RStudio Server versions correspondance

In order to get coherent versioned Rocker containers, versions of R, R packages,
and RStudio Server are match on a time scale by default. Change MRAN date for
`rocker/r-ver` using e.g. (from the corresponding dir):

```
docker build --build-arg BUILD_DATE=2017-10-31 -t rocker/r-ver:3.4.2 .
```

Change RStudio Server version for `rocker/rstudio` using, e.g. (from the
corresponding dir):

```
docker build --build-arg RSTUDIO_VERSION=1.1.414 -t rocker/rstudio:3.4.2 .
```


## Rules

- Docker tags correspond to the version of R included on the image.

- The default docker tag, `latest`, is now identical to the image tagged with
  the current version.  `latest` and `devel` tags are built nightly.

- MRAN date is the last date CRAN distributed that R version.

- RStudio Server version (and date) from http://download2.rstudio.org/ as the
  version that was available at MRAN date.

<!-- (tags may not always be available)
- Docker tags specifying only the minor (`3.4`) or major version (`3`) are also
  available. Requesting a minor version `3.4` will automatically correspond to
  the highest available patch number (`3.4.4`).
