无法使用 Windows 10 在 Rstudio 中编译 rstan 或 Rcpp 代码

Question

I am not managing to compile Rcpp or rstan code on Windows.

When I try to compile an rstan program (below) I receive the error

Error in compileCode(f, code, language = language, verbose = verbose) : In file included from C:/Users/thean/AppData/Local/Temp/Rtmp0kEsrn/downloaded_packages/rJava_0.9-13.zip/Rcpp/include/RcppCommon.h:29, from C:/Users/thean/AppData/Local/Temp/Rtmp0kEsrn/downloaded_packages/rJava_0.9-13.zip/Rcpp/include/Rcpp.h:27,

from file18045ecf22e4.cpp:7:C:/Users/thean/AppData/Local/Temp/Rtmp0kEsrn/downloaded_packages/rJava_0.9-13.zip/Rcpp/include/Rcpp/r/headers.h:71:10: fatal error: Rh: No such file or directory #include <Rh>
^~~~~compilation terminated.make: *** [C:/PROGRA~1/R/R-40~1.1/etc/x64/Makeconf:229: file18045ecf22e4.o] Error 1

If I try to run the following within Rstudio it redownloads Rtools but it has been already downloaded

library(Rcpp); evalCpp("2+2") 

And running

Sys.which("make") 
"C:\\rtools40\\usr\\bin\\make.exe" 

Additionally, when I run Sys.which("make") in the command window it just has "" , and not the "C:\\rtools40\\usr\\bin\\make.exe". When I run library(Rcpp); evalCpp("2+2") library(Rcpp); evalCpp("2+2") it produces the original error of this tread

The original question was related to receiving an error when trying to compile an rstan program.

I'm using the code below

library(StanHeaders)

library(rstan) 
values = list(y = rnorm(1000,5,3)) 

model =" 

data { 
real y[1000]; 
} 

parameters { 
real mu; 
real sigma; 
} 

model { 
mu    ~ normal(0,10);   
sigma ~ normal(0,10);  
y     ~ normal(mu,sigma); 
} 
" 

fit <- stan(model_code = model, data = values, warmup = 500, iter = 1000, 
chains = 4, cores = 2, thin = 1) 
posterior = extract(fit) 

I keep getting this error message:

Error in compileCode(f, code, language = language, verbose = verbose) : 
  In file included from C:/Users/thean/AppData/Local/Temp/Rtmp0kEsrn/downloaded_packages/rJava_0.9-13.zip/Rcpp/include/RcppCommon.h:29,                 from C:/Users/thean/AppData/Local/Temp/Rtmp0kEsrn/downloaded_packages/rJava_0.9-13.zip/Rcpp/include/Rcpp.h:27,                 
    from file18045ecf22e4.cpp:7:C:/Users/thean/AppData/Local/Temp/Rtmp0kEsrn/downloaded_packages/rJava_0.9-13.zip/Rcpp/include/Rcpp/r/headers.h:71:10: fatal error: R.h: No such file or directory #include <R.h>          ^~~~~compilation terminated.make: *** [C:/PROGRA~1/R/R-40~1.1/etc/x64/Makeconf:229: file18045ecf22e4.o] Error 1

When I go to this directory I don't have Rcpp.h:27 but I do have Rcpp.h. Its like this on all the files. Please help. Thanks

As it wasn't mentionned, it could simply be a path problem.

Putting Rtools on the PATH

After installation is complete, you need to perform one more step to be able to compile R packages: you need to put the location of the Rtools make utilities (bash, make, etc) on the PATH.

Try to execute once in R console following command:

writeLines('PATH="${RTOOLS40_HOME}\\usr\\bin;${PATH}"', con = "~/.Renviron")

This last step is necessary after Rtools installation .
