First: this is not a bug, more a feature request.
Secondly, even if it was a bug, it is _not_ a bug in R, please read
the posting rules for bugs. Now a member of R-core has to use
valuable time to clean up after your bug report.
Correspondence such as this such really be sent to the package
maintainers (and - perhaps - a cc to R-devel).
Having said all of this, of course it would be nice if svn supported
sparse matrices.
