內聯和Rcpp包的錯誤

我在Windows 7上使用R 2.15.1，並在運行以下R代碼時收到錯誤消息。有人幫我嗎？內聯和Rcpp包的錯誤

+ return wrap(as<int>(x) * as<double>(y)) ;

除了Dirk的回答下面，你可以關注這個帖子，作者有問題。 http://www.r-bloggers.com/installing-rcpp-on-windows-7-for-r-and-c-integration/ –

這是一個令人費解的帖子。在許多教程中解釋瞭如何在Windows上安裝R的編譯器。總之，不要與Cygwin混合使用。 –

在這裏工作在Linux下（雖然我做了小改動/簡化）：

R> library(inline) 
R> fx <- cxxfunction(signature(x = "integer", y = "numeric"), 
+     body = 'return wrap(as<int>(x) * as<double>(y));', 
+     plugin = "Rcpp") 
R> print(fx(2, 2.5)) 
R> [1] 5 
R>

如果設置環境變量CYGWIN到nodosfilewarning你會得到線噪聲少一點點在Windows上。

謝謝，但我不知道環境變量。我剛剛在Windows 7上安裝了R，R工具和CYGWIN – user1690124

您可能需要了解有關Windows計算機的管理... –
