Defunct Functions in Base Package

Description:

     The functions or variables listed here are no longer part of R as
     they are not needed (any more).

Usage:

     Version()
     provide(package)
     .Provided
     category(...)
     print.anova.glm(.)
     print.anova.lm(.)
     print.tabular(.)
     print.plot(.)
     save.plot(.)
     system.test(.)
     getenv(...)
     read.table.url(url, method,...)
     scan.url(url, file = tempfile(), method, ...)
     source.url(url, file = tempfile(), method, ...)
     httpclient(url, port=80, error.is.fatal=TRUE, check.MIME.type=TRUE,
                file=tempfile(), drop.ctrl.z=TRUE)
     parse.dcf(text = NULL, file = "", fields = NULL, versionfix = FALSE)
     .Alias(expr)
     print.ordered(.)
     .Dyn.libs
     .lib.loc
     machine()
     Machine()
     Platform()
     restart()
     printNoClass(x, digits = NULL, quote = TRUE, na.print = NULL,
                  print.gap = NULL, right = FALSE, ...)
     codes(x, ...)
     codes(x, ...) <- value
     print.atomic(x, quote = TRUE, ...)
     La.eigen(x, symmetric, only.values = FALSE, method = c("dsyevr", "dsyev"))
     tetragamma(x)
     pentagamma(x)
     package.description(pkg, lib.loc = NULL, fields = NULL)
     loadURL(url, envir = parent.frame(), quiet = TRUE, ...)
     delay(x, env = .GlobalEnv)
     format.char(x, width = NULL, flag = "-")
     La.chol(x)
     La.chol2inv(x, size = ncol(x))
     symbol.C(name)
     symbol.For(name)
     unix(call, intern = FALSE)

Details:

     '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. They were
     never used for their intended purpose, to allow one package to
     subsume another.

     'getenv' has been replaced by 'Sys.getenv'.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     'parse.dcf' has been replaced by 'read.dcf', which is much faster,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 <URL: http://developer.r-project.org>.

     '.Dyn.libs' and '.lib.loc' were internal variables used for
     storing and manipulating the information about packages with
     dynloaded shared libs, 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 calls 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 an alphabetical
     ordering of the levels in the locale in use.

     'print.atomic' differed from 'print.default' only in its argument
     sequence.  It is not a method for 'print'.

     'La.eigen' has become the default for 'eigen'.

     'tetragamma' and 'pentagamma' have been replaced by 'psigamma'.

     'package.description' has been replaced by 'packageDescription' in
     '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' are 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.
