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
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getenv has been replaced by
httpclient was used by the deprecated
"socket" method of
parse.dcf has been replaced by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 http://developer.r-project.org.
.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
printNoClass was in package methods and called directly the internal function
codes was almost always used inappropriately. To get the internal coding of a factor, use
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
pentagamma have been replaced by
package.description has been replaced by
packageDescription in package utils.
delay has been replaced by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
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 (Γ) 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.
.S3method were part of an experimental alternative way to specify namespaces.
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.
.saveRDS, were internal-only versions (and the only versions available prior to R 2.13.0) of
