Hello, stan community!

Additional discussion on problem I am dealing with could be found [there](https://stackoverflow.com/questions/52721672/r-stan-8schools-example-faile/52724262?noredirect=1#comment92374693_52724262)

I am trying to run classical r-stan example from this official [tutorial](https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started#how-to-use-rstan). But I can’t because I get the following error message:

 ![](https://canada1.discourse-cdn.com/flex030/uploads/mc_stan/original/2X/9/9df0065d73296264fd01ed754cf79d888797a53c.png)

[Ben Goodrich](https://stackoverflow.com/users/1762912/ben-goodrich) suggested to set Sys.setenv(USE\_CXX14=1) and include the following lines to Makevars file:

CXX14=g++  
CXX14FLAGS=-O3

But I still get the same error message. I also have been trying to install.packages(“[https://win-builder.r-project.org/OdTz9MCBT96j/rstan\_2.18.1.zip](https://win-builder.r-project.org/OdTz9MCBT96j/rstan_2.18.1.zip)”, repos = NULL) but then I can’t run library(‘rsatn’) as I get:

Error: package or namespace load failed for ‘rstan’ in rbind(info, getNamespaceInfo(env, “S3methods”)):  
number of columns of matrices must match (see arg 2)

Please help me to figure out this problem.

Will be very greatfull for help!

When you get the error involving `rbind(info, getNamespaceInfo(env, "S3methods"))`, can you post the output of `traceback()`. Also, when restarting R you have to make sure that there are no `stanfit` objects being autoloaded into your session via the `.RData` file in the startup directory.

Is it working now?

If you do `require(rstan)` instead of `library(rstan)` does it give you anything different?

It gives the same error message.

OK. Maybe do `remove.packages("rstan")`, restart R cleanly, do `install.packages("rstan")` but then put

```
CXX14 = g++ -std=c++1y
CXX14FLAGS = -O3 -Wno-unused-variable -Wno-unused-function

```

into your ~/.R/Makevars file before trying to compile any Stan models.

Hello, Ben!

Sorry for nonresponding for so loing as I was extremely bussy.

I made these steps but then I get the following message:

If `cat(strsplit(Sys.getenv(“PATH”), “;”)[[1]], sep = “\n”)` shows anything pertaining to mingw\_32 (which appears likely), then you need to remove it from your PATH using something like

> OK, according to @paul.buerkner , the problem is the presence of C:\Rtools\mingw\_32\bin in your PATH. To delete this, click something like left-click on Start right-click on Computer left-click on Properties left-click on Advanced System Settings left-click on Environmental variables scroll down in the bottom window to Path and left-click it left-click Edit move the cursor all the way to the left then delete the part that says C:\Rtools\mingw\_32\bin; (be sure to delete exactly one semi-colon) l…

Thank you for detailed steps! I has been following them carefully. And I get 10. However, I still get the error when trying to build a model:

Error in compileCode(f, code, language = language, verbose = verbose) :  
Compilation ERROR, function(s)/method(s) not created! g++: not found

My path looks like ![Rtools](https://canada1.discourse-cdn.com/flex030/uploads/mc_stan/original/2X/c/c870dfb91e631ea4cdfaed787e80e61e9e0e0553.png)

You should uninstall Rtools 3.4 and then make sure your path has nothing pertaining to `mingw_32` or `mingw_64`. Once you do that, you can also try

```
pkgbuild::has_build_tools(debug = TRUE)

```

I made these steps and the commant returns TRUE. But the error reamins the same when I am building the model.

I have totally reinstalled all R related stuff following new installation guide [https://github.com/stan-dev/rstan/wiki/Installing-RStan-on-Windows](https://github.com/stan-dev/rstan/wiki/Installing-RStan-on-Windows)

Now all works greate! Thank you very much for your exensive help!

P.S. While installing R-tools I made my path look exactly like tutorial ones removeing all other rows.
