I've rolled up R-1.8.1.tgz a short while ago. This is a patch version
mostly fixing a number of issues in 1.8.0, some of which were quite
serious. As usual, a few new features have crept in as well. (See below
for details.)
You can get it from
http://cran.us.r-project.org/src/base/R-1.8.1.tgz
or wait for it to be mirrored at a CRAN site nearer to you. Binaries
for various platforms will appear in due course.
There is also a version split for floppies.
These are the md5sums for the freshly created files, in case you wish
to check that they are uncorrupted:

Here's the relevant part of the NEWS file
CHANGES IN R VERSION 1.8.1
NEW FEATURES
o There is now a "Complex" S3 group generic (a side-effect of
fixing up the corresponding S4 group generic).
o help("regex") now gives a description of the regular expressions
used in R.
o The startup message now shows the R Foundation as copyright
holder, and includes the R ISBN number and a pointer to the new
citation() function.
o The solve() function now uses the `tol' argument for all
non-complex cases. The default tolerance for LINPACK is 1e-7,
as before. For LAPACK it currently is .Machine$double.eps but
may be changed in later versions of R.
o help.search() now defaults to agrep = FALSE when keyword= is
specified, since no one wants fuzzy matching of categories.
o Function texi2dvi() in package tools can be used to compile
latex files from within R.
o Objects with formal S4 classes saved in pre-1.8 versions and
loaded into the current version have incompatible class
attributes (no package information). A new function,
fixPre1.8() in package methods, will fix the class attributes.
See the help for this function.
o heatmap() allows Rowv/Colv = NA, suppressing the corresponding
dendrogram.
o An "antifeature": Tcl 8.0 is now officially unsupported. In
1.8.0
it just didn't work. This very old version lacks several features
that are needed for the new version of the tcltk package. R will
still build the tcltk package against Tcl 8.0 but the resulting
package will not load.
BUG FIXES
o symnum(x) now behaves as documented when length(x) == 0 and uses
lower.triangular = FALSE for logical arrays.
o c() now has a method for "noquote" objects and hence works as
expected.
o split(1:10, c(1,2)) no longer gives a spurious warning.
o The "Complex" S4 group generic now works.
o abbreviate() doesn't get into infinite loops on input that differs
only by leading/trailing space
o Added check for user interrupt in Rvprintf to allow printing to be
interrupted.
o Fixed bug that would cause segfault on protect stack overflow.
o crossprod() on matrices with zero extents would return an
uninitialized matrix (rather than one filled with zeros).
o DF[[i,j]] for a data frame used row j and col i, not as intended
row i and col j.
o Even more user errors in recursive indexing of lists are now
caught. (PR#4486)
o cor(<matrix>, use = "pairwise") gave wrong result in 1.8.0
(only).
(PR#4646)
o merge.data.frame() could give incorrect names when one of the
arguments had only one column. (PR#4299)
o Subsetting a one-dimensional array dropped dimensions even when
they were not of length one. (Related to PR#4110)
o The plot() method for `ecdf' objects, plot.ecdf(), now allows to
set a `ylab' argument (different from the default).
o cor.test(*, method="spearman") gave wrong results `randomly'
(because of a wrong type passed to C; PR#4718).
o dist() objects with NA's didn't print these, now do. (PR#4866).
o regexpr(fixed = TRUE) returned 0-based indices.
o df[, length_1_index] <- value did not recycle short rhs. (PR#4820)
o median() no longer `works' for odd-length factor variables.
o packageStatus() is more robust to failing to contact a
repository, and contacts the correct paths in the repositories
under Windows.
o .setOldIs (methods) contained a typo stopping POSIXct objects (etc)
being included in formal classes.
o terms() sometimes removed offset() terms incorrectly, since it
counted by variables and not terms. Its "offset" attribute
was incorrectly documented as referring to terms not
variables. (Related to PR#4941)
o buildVignettes() and pkgVignettes() in package tools are now
documented. The call to texi2dvi is wrapped in the new
function texi2dvi() which also works on Windows.
o hclust() was sometimes not finding the correct inter-cluster
distances with non-monotone methods. (PR#4195)
o plot.hclust() now tolerates mode changes on dumped objects. (PR#4361)
o prompt() no longer insists files are in the current directory.
(PR#4978)
o filter() did not use init in reverse order as documented. (PR#5017)
o contrasts<-() and model.matrix() now have sanity checks that
factors having at least 2 levels (or one level and a contrast
matrix): model.matrix() gave nonsensical results for 0-level
factors.
o writeChar() could segfault if more characters were requested
than exist. (PR#5090)
o round() and signif() dropped attributes with 0-length inputs,
only. (PR#4710)
o The default graphics device in the GNOME interface was gtk,
which is no longer in the base package. It is now X11.
o The print button on the toolbar of the GNOME graphics device
did not work.
o The example code on the man page for TkWidgetcmds had not been
updated after the change that made tkget (et al.) return
tclObj objects, so the "Submit" button didn't work.
o Rd conversion to latex did not add a new line before
\end{Section} for the section environments, which caused
problems if the last thing in a section was \preformatted{}
(and potentially elsewhere).
o Under some circumstances mosaicplot() failed if main was
supplied as it was passed on to model.frame.default().
o Conversion to POSIXlt (including printing) of POSIXct dates
before 1902 and after 2038 computed which were leap years from
(year-1900) so got some xx00 years wrong.
