在R版本3.0.2上安装Rtools

Question

我已经为R安装了devtools，但是当我使用以下命令调用库时：

library(devtools)

我得到以下输出：

WARNING: Rtools is required to build R packages, but is not currently installed.
Please download and install Rtools 3.1 from http://cran.r-project.org/bin/windows/Rtools/ and then run find_rtools().

所以我执行了以下代码：

install.packages("Rtools", repos = "http://cran.r-project.org/bin/windows/Rtools/")

并且我得到以下输出：

Installing package into ‘C:~/Documents/R/win-library/3.0’
(as ‘lib’ is unspecified)
Warning: unable to access index for repository http://cran.r-project.org/bin/windows/Rtools/bin/windows/contrib/3.0
Warning message:
package ‘Rtools’ is not available (for R version 3.0.2)

我很高兴能将Rtools安装到我的机器上，因此我可以调用devtools库。谢谢！

Rtools不是软件包。看到这里：https://cran.r-project.org/bin/windows/Rtools/
