Some of these have stubs which report that they are defunct, but most have been removed completely (apart from being documented here).
category has been an old-S function before there were factors;
should be replaced by factor throughout!
The new function dev.print() should now be used for saving
plots to a file or printing them.
provide and its object .Provided have been removed.
Their intended purpose was to allow one package to subsume another,
but this was never used.
getenv has been replaced by Sys.getenv.
*.url are replaced by calling read.table, scan or
source on a url connection.
httpclient was used by the deprecated "socket" method
of download.file.
parse.dcf has been replaced by read.dcf, which is much
faster, but has a slightly different interface.
.Alias provided an unreliable way to create duplicate
references to the same object. There is no direct replacement. Where
multiple references to a single object are required for semantic
reasons consider using environments or external pointers. There are
some notes on https://developer.r-project.org.
.Dyn.libs and .lib.loc were internal variables used for
storing and manipulating the information about packages with DLLs, and
the known R library trees. These are now dynamic variables which one
can get or set using .dynLibs and
.libPaths, respectively.
Machine() and Platform() were functions returning the
variables .Machine and .Platform
respectively.
restart() should be replaced by try(), in preparation
for an exception-based implementation. If you use restart() in
a way that cannot be replaced with try() then ask for help
on r-devel.
printNoClass was in package methods and called directly the
internal function print.default.
codes was almost always used inappropriately. To get the
internal coding of a factor, use unclass, as.vector or
as.integer. For ordered factors, codes was
equivalent to these, but for unordered factors it assumed an
alphabetical ordering of the levels in the locale in use.
La.eigen has become the default for eigen.
tetragamma and pentagamma have been replaced by
psigamma.
package.description has been replaced by
packageDescription in package utils.
loadURL has been superseded by load(url()).
delay has been replaced by delayedAssign.
Unevaluated promises should never be visible.
write.table0 was an R-level version of write.table
provided for temporary back-compatibility.
format.char was an auxiliary function for formatC
whose functionality (and more) is provided by format.default.
La.chol and La.chol2inv became the default methods for
chol and chol2inv.
Functions symbol.C and symbol.For were provided for
historical compatibility with S. symbol.C just returns its
argument unchanged, whereas symbol.For will map to lower case
and append an underscore on those platforms (almost all) which do so
for Fortran symbols. These are no longer of any use in R.
unix was a deprecated (since the 1990s) alternative to
system, available for backwards compatibility with S.
gammaCody was the \((\Gamma)\) function from the Specfun
package used at C level in the Bessel code. The R-level interface was
here for experimental purposes.
manglePackageName was part of the defunct support for versioned
installs.
.Import, .ImportFrom, .Export and
.S3method were part of an experimental alternative way to
specify namespaces.
.First.lib was the load/attach hook for packages without
namespaces: use .onLoad or .onAttach instead.
mem.limits reported on the old-style limits on the number of
cons cells and size of the vector heap. These are no longer limited
except by overall memory limits.
.readRDS and .saveRDS, were internal-only versions (and
the only versions available prior to R 2.13.0) of
.readRDS and .saveRDS.
Sys.putenv was a synonym for Sys.setenv,
deprecated since R 2.5.0.
real, as.real and is.real were long-deprecated
synonyms for the double versions.
.find.package and .path.package were internal-only
versions prior to R 2.13.0, and since deprecated wrappers for
find.package and path.package.
