R 2.XX.Y 中的核心包

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

1）您可以查看来源。

2）问题甚至不清楚included也受到推崇的图书馆。大多数人会理解你的问题是要求两组。

3) 在 Debian 上，我们分割了安装目录，这样可以轻松回答问题 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）查看源代码可以看出真正的默认值和推荐值之间的区别：（这些是来自版本化 tarball 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

and

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，包还在其描述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/spatial/DESCRIPTION:Priority: recommended
/usr/lib/R/library/survival/DESCRIPTION:Priority: recommended
edd@max:~$ 

and

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

edd@max:~$ 

所有这些答案都是针对 2.14.1 的。
