I had Rstan running, it took one hour for my computer while it took 1 minute on other people’s computer. So I decided to reinstall R, Rstudio, Rstan, and Rtools. However, after I re-installed everything,
- it runs fine for extremely simple code,
- regular IRT takes 10 minutes too run (too long),
- my regular model will not run. It gives the error “Error: cannot allocate vector of size 16687.6 Gb
In addition: Warning message:
In system(paste(CXX, ARGS), ignore.stdout = TRUE, ignore.stderr = TRUE) :
‘C:/rtools40/usr/mingw_/bin/g++’ not found”
I suspect the installation is not perfect, and tried all the suggestions I got from the internet and other people, but still doesn’t work. I’d really appreciate it if you could help.
