我将操作系统升级到El Capitan，现在我在R中发布了一个安装包命令 install.packages（ 'MASS'） 我收到以下错误：
/usr/local/Cellar/r/3.2.3/R.framework/Resources/include/R_ext/Constants.h:33:10: fatal error: 'float.h' file not found
#include <float.h> /* Defines the rest, at least in C99 */
我的标准c ++库中有float.h：
ls /usr/include/c++/4.2.1/tr1/float.h
/usr/include/c++/4.2.1/tr1/float.h
但是R是由家庭酿造安装的，正在看酒窖。
我认为El Capitan的路径在R中没有正确链接，所以我卸载了R，并重新安装了它。现在，当我尝试安装旧R安装的软件包（如ggplot2）时，我收到此错误。我看过很多关于El Capitain打破开发者工具的帖子（比如这个：https://ohthehugemanatee.org/blog/2015/10/01/how-i-got-el-capitain-working-with-my-developer-tools/），但没有任何关于R的内容。
这是El Capitan的R或家酿的问题吗？有没有办法告诉R在哪里寻找这些标题？任何其他建议也会非常有用。
install.packages（'MASS'）的完整输出如下：

编辑：42指出CRAN的R版本比brew更好。我卸载了R（brew uninstall R）并从CRAN（http://cran.us.r-project.org）下载并安装了R，现在可以使用了。
Edit2：在评论中，hrbrmstr指出，在El Capitan升级之后，home-brew需要一个干净的安装。我没有尝试过这种方法，但我想指出它可能会起作用。
