The warning for axis()(-like) calls in cases of relatively small ranges (typically in log-scale situations) is slightly improved _and_ suppressed from explicit calls to.Environment variables R_LIBS_USER and R_LIBS_SITE are both now set to the R system default if unset or empty, and can be set to NULL to indicate an empty list of user or site library directories.simplify2array() gains an except argument for controlling the exceptions used by sapply().The description of capabilities("http/ftp") now reflects that it refers to the default method, no longer the internal one. Function file_test() in package utils gains tests for symlinks, readability and writability.This warning can be turned into an error by setting environment variable _R_CHECK_MATRIX_DATA_ to TRUE: R CMD check -as-cran does so unless it is already set. matrix(x, n, m) now warns in more cases where length(x) differs from n * m, as suggested by Abby Spurdle and Wolfgang Huber in Feb 2021 on the R-devel mailing list.The default locations for the R installation and personal library folder have been changed.UTF-8 locales are used where available.
Support for 32-bit builds has been dropped.Windows users should consult the WINDOWS section below for some profound changes including.Consequently, environment variable _R_CHECK_LENGTH_1_CONDITION_ no longer has any effect. Calling if() or while() with a condition of length greater than one gives an error rather than a warning.Calling & or || with either argument of length greater than one now gives a warning (which it is intended will become an error).This means that calling aggregate() with a formula as a named first argument requires name formula in earlier versions of R and name x now, so portable code should not name the argument (code in many packages did). The formula method of aggregate() now matches the generic in naming its first argument x (resolving PR#18299 by Thomas Soeiro).De changelog van deze uitgave ziet er als volgt uit: Significant User-Visible Changes: Het R-coreteam, dat zich vandaag de dag bezighoudt met de doorontwikkeling, heeft versie 4.2.0 uitgebracht met de titel Vigorous Calisthenics. In R is programmeren sterk objectgeoriënteerd en de functionaliteit kan uitgebreid worden via packages die onder andere via cran beschikbaar worden gesteld. Het werd oorspronkelijk ontworpen door Ross Ihaka en Robert Gentleman (vandaar de naam R) aan de Universiteit van Auckland, Nieuw-Zeeland. R is een ontwikkelomgeving en programmeertaal voor statistische en data-analysedoeleinden.
