You can check out a specific revision of the R sources with
svn checkout -r 1234 https://svn.r-project.org/R/trunk/ $TOP_SRCDIROccasionally, the latest revision of the R sources does not pass make check.
In this case, it can be a good idea to revert to an earlier revision until the R Core Team have made further updates to fix the issue.
Visit the Build from SVN page that summarises attempted builds of R using GitHub actions on the unofficial GitHub mirror. Find the latest run that completed successfully (green checkmark) and use the commit message to search for the corresponding Subversion revision. For example, to search the last 10 revisions for the log message "More @apifun and such annotations"
cd $TOP_SRCDIR
svn log --limit 10 --search "More @apifun and such annotations"/workspaces/r-dev-env/svn/r-devel $ svn log --limit 10 --search "More @apifun and such annotations"

If you have already attempted to build R, you can re-run the make with the version identified in your search as follows:
svn checkout -r 86726 https://svn.r-project.org/R/trunk/ $TOP_SRCDIR
cd $BUILDDIR
make
make check
Otherwise, follow the full instructions in Building R, updating the svn checkout command to use the required revision.
