Question

我想使用Rcpp，但是当我使用cppFunction（）时，我收到一条消息来安装Rtools，如下所示。

即使我安装它，我也想继续安装。

当我使用3.4.1时，我曾经拥有它，但是我遇到了问题，所以我删除了它并安装了版本3.4.2。

也许有一个原因，但我不知道如何解决它。我使用以下代码删除所有包并重新安装Rcpp。

> cppFunction("
+             NumericVector insertsortcpp(NumericVector vector) {
+             int n = vector.size();
+             double tmp;
+             for(int i=1; i<n; i=i+1) {
+             tmp=vector[i];
+             int j=i-1;
+             while(j>=0 && vector[j]>tmp) {
+             vector[j+1]=vector[j];
+             j=j-1;
+             }
+             vector[j+1]=tmp;
+             }
+             return vector;
+             }")

我知道很多问题，但我无处可问。

感谢您的帮助。
