I want to use Rcpp, but when I use cppFunction (), I get a message to install Rtools as shown below.
I would like to continue installing even if I install it.
I used to have it when I used 3.4.1, but I have a problem, so I erased it and installed version 3.4.2.
Maybe there is a cause, but I do not know how to solve it. I use the following code to delete all packages and re-install 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;
+ }")

I know it's a lot of questions, but I have no place to ask.
I would appreciate your help.
