R 2.XX.Y中的核心包

Question

我想知道如何知道哪些包是核心的R 2.XX.Y.假设我安装.R 2.14.1然后这个版本将附带哪些软件包.谢谢

Answer 1

1)你可以查看来源.

2)问题甚至不清楚,因为包括以及推荐的库.大多数人会将你的问题理解为要求两套.

3)在Debian上,我们拆分安装目录,这样就可以轻松地回答问题2):

edd@max:~$ ls /usr/lib/R/library/         ## 
base       datasets    lattice  nnet      stats4
boot       foreign     MASS     parallel  survival
class      graphics    Matrix   rpart     tcltk
cluster    grDevices   methods  spatial   tools
codetools  grid        mgcv     splines   utils
compiler   KernSmooth  nlme     stats

4)查看源代码可以分析真正的默认值和推荐值:(这些是来自版本化tar包的软链接)

edd@max:~$ COLUMNS=60 ls ~/src/debian/R/R-2.14.1/src/library/
base      grDevices     methods      splines  tools
compiler  grid          parallel     stats    utils
datasets  Makefile.in   profile      stats4
graphics  Makefile.win  Recommended  tcltk

和

edd@max:~$ COLUMNS=60 ls ~/src/debian/R/R-2.14.1/src/library/Recommended/
boot_1.3-3.tar.gz         MASS_7.3-16.tar.gz
boot.tgz                  MASS.tgz
class_7.3-3.tar.gz        Matrix_1.0-2.tar.gz
class.tgz                 Matrix.tgz
cluster_1.14.1.tar.gz     mgcv_1.7-12.tar.gz
cluster.tgz               mgcv.tgz
codetools_0.2-8.tar.gz    nlme_3.1-102.tar.gz
codetools.tgz             nlme.tgz
foreign_0.8-48.tar.gz     nnet_7.3-1.tar.gz
foreign.tgz               nnet.tgz
KernSmooth_2.23-7.tar.gz  rpart_3.1-50.tar.gz
KernSmooth.tgz            rpart.tgz
lattice_0.20-0.tar.gz     spatial_7.3-3.tar.gz
lattice.tgz               spatial.tgz
Makefile.in               survival_2.36-10.tar.gz
Makefile.win              survival.tgz
edd@max:~$ COLUMNS=60 

5)最后,软件包还在其DESCRIPTION字段中说明了这一点:

edd@max:~$ grep -i Recommended /usr/lib/R/library/*/DESCRIPTION
/usr/lib/R/library/boot/DESCRIPTION:Priority: recommended
/usr/lib/R/library/class/DESCRIPTION:Priority: recommended
/usr/lib/R/library/cluster/DESCRIPTION:Priority: recommended
/usr/lib/R/library/codetools/DESCRIPTION:Priority: recommended
/usr/lib/R/library/foreign/DESCRIPTION:Priority: recommended
/usr/lib/R/library/KernSmooth/DESCRIPTION:Priority: recommended
/usr/lib/R/library/lattice/DESCRIPTION:Priority: recommended
/usr/lib/R/library/MASS/DESCRIPTION:Priority: recommended
/usr/lib/R/library/Matrix/DESCRIPTION:Priority: recommended
/usr/lib/R/library/mgcv/DESCRIPTION:Priority: recommended
/usr/lib/R/library/nlme/DESCRIPTION:Priority: recommended
/usr/lib/R/library/nnet/DESCRIPTION:Priority: recommended
/usr/lib/R/library/rpart/DESCRIPTION:Priority: recommended
/usr/lib/R/library/spatial/DESCRIPTION:Priority: recommended
/usr/lib/R/library/survival/DESCRIPTION:Priority: recommended
edd@max:~$ 

和

edd@max:~$ grep "Priority: base" /usr/lib/R/library/*/DESCRIPTION
/usr/lib/R/library/base/DESCRIPTION:Priority: base
/usr/lib/R/library/compiler/DESCRIPTION:Priority: base
/usr/lib/R/library/datasets/DESCRIPTION:Priority: base
/usr/lib/R/library/graphics/DESCRIPTION:Priority: base
/usr/lib/R/library/grDevices/DESCRIPTION:Priority: base
/usr/lib/R/library/grid/DESCRIPTION:Priority: base
/usr/lib/R/library/methods/DESCRIPTION:Priority: base
/usr/lib/R/library/parallel/DESCRIPTION:Priority: base
/usr/lib/R/library/splines/DESCRIPTION:Priority: base
/usr/lib/R/library/stats4/DESCRIPTION:Priority: base
/usr/lib/R/library/stats/DESCRIPTION:Priority: base
/usr/lib/R/library/tcltk/DESCRIPTION:Priority: base
/usr/lib/R/library/tools/DESCRIPTION:Priority: base
/usr/lib/R/library/utils/DESCRIPTION:Priority: base
edd@max:~$ 

所有这些答案都是针对2.14.1.

Answer 2

或者您也可以使用:

installed.packages(priority = "base")
