r - R 2.XX.Y 中的核心包

Question

我想知道如何知道 R 2.XX.Y 中哪些包是核心.假设我安装。 R 2.14.1那么这个版本会附带哪些软件包。谢谢

Answer 1

1)您可以查看来源。

2)问题甚至不清楚，因为包含以及​​推荐的库。大多数人会将您的问题理解为要求两组。

3) 在 Debian 上，我们拆分了安装目录，这样可以很容易地回答问题 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)查看源代码可以区分真实默认值和推荐值:(这些是来自版本化 tarball 的软链接(soft link))

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，包在他们的描述字段中也这样说:

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/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/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 的。
