我试图在我的Amazon EC2实例上安装RTextTools for R。我用的是r3.1.1。(2014-07-10安装)与亚马逊的Linux AMI。我以root权限打开R并尝试以下操作:
> install.packages('RTextTools')
Installing package into ‘/root/R/x86_64-redhat-linux-gnu-library/3.1’
(as ‘lib’ is unspecified)

问题似乎是没有Rblas。我:
- 尝试分别安装slam, tm和maxent
- 确认gcc已安装
- 安装其他R包(Zelig, ggplot2)没有问题
- 阅读这些SO问题。
- 试图理解进入链接描述这里的R文档在BLAS
我认为问题是R寻找不同版本的BLAS比gcc使用。但我真的不知道。我不希望重新安装R，因为它在服务器上被大量使用。
我该怎么办?
明白了。Amazon的默认机器映像使用Atlas BLAS。R指出，当安装所有默认值时，但RTextTools期望普通的BLAS。我卸载了Atlas，卸载了R，重新安装了R，然后就可以安装RTextTools了。
