我无法让 Rcpp 在 Windows 8.1 上工作。当我运行以下最小示例时,出现错误。

> evalCpp("1 + 1")

我的路径中的前两个条目是:
PATH=c:\Rtools\bin;c:\Rtools\gcc-4.6.3\bin;
R 安装在目录 C:\R\R-3.1.0
Rtools 位于目录 C:\R\Rtools

最佳答案
不确定您是否已经解决了您的问题,但您似乎没有安装 gcc 或 g++。对于 Windows,您可以使用 MinGW 获取这些工具。
require(Rcpp); evalCpp("1 + 1")
再次。 关于r - 如何让 Rcpp 工作?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/23458841/
