我制作了一个包含 /scr 文件夹的包,我想在 Windows 7 中安装它。我安装了 Rtools for Windows 以防出现任何编译器问题,但是当我运行时:
> install.packages("mypackage.tar.gz", repos="NULL", type="source")
我仍然收到如下错误消息:
Installing package(s) into ‘C:/Users/UserName/Documents/R/win-library/2.15’
(as ‘lib’ is unspecified)
Warning: unable to access index for repository NULL/src/contrib
Warning message:
package ‘mypackage.tar.gz’ is not available (for R version 2.15.1)
这是我的会话信息():

在 Windows 7 中从源代码(使用 /src)安装 R 包是否缺少任何东西?谢谢!
