在R版本3.0.2上安装Rtools

Question

我已经为R安装了devtools，但是当我用以下方法调用库时：

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().

因此，我执行了以下代码：

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

我得到了以下输出：

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)

我希望有任何帮助，让Rtools在我的机器上，以便我可以打电话给devtools库。谢谢!

Rtools不是一个包。见此处：https://cran.r-project.org/bin/windows/Rtools/
