“Do you want to install from sources the packages which need compilation?”
Yes?
Yes
Instead of the warning message you indicated, I got:
Warning message:
In example(stan_model, run.dontrun = TRUE) : no help found for ‘stan_model’
Thank you for all your help by the way
Oops, I forgot to include the instruction to load RStan first:
library(rstan)
example(stan_model,run.dontrun = TRUE)
This looks like what you were talking about (below), but I am still getting errors in RStudio when trying to run rstan commands or install rethinking.
library(rstan)
Loading required package: StanHeaders
Loading required package: ggplot2
rstan (Version 2.21.2, GitRev: 2e1f913d3ca3)
For execution on a local, multicore CPU with excess RAM we recommend calling
options(mc.cores = parallel::detectCores()).
To avoid recompilation of unchanged Stan programs, we recommend calling
rstan_options(auto_write = TRUE)
Do not specify ‘-march=native’ in ‘LOCAL_CPPFLAGS’ or a Makevars file
example(stan_model,run.dontrun = TRUE)

stn_md> mod <- stan_model(model_code = stancode, verbose = TRUE)

In addition: Warning message:

Something else I missed!
Can you try running:
dotR <- file.path(Sys.getenv("HOME"), ".R")
if (!file.exists(dotR)) dir.create(dotR)
M <- file.path(dotR, "Makevars.win")
if (!file.exists(M)) file.create(M)
cat("\nCXX14FLAGS += -O3 -mtune=native -mmmx -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2",
file = M, sep = "\n", append = FALSE)
And then restart R and try the example again?

It ran a bunch of code and eventually spat out (below). In a new markdown file, I tried calling the rstan library and am still getting no package called rstan. I have to put this away for now but I really appreciate your help and will check back later.
<U+2714> Packages successfully installed.
There were 50 or more warnings (use warnings() to see the first 50)
OS X:
Install R >4.0.1 , latest RStudio Desktop, latest Xcode development toolkit (check with xcode-select --install in the terminal), install rstan.
For fortran I don’t recall where I got it from, but my Makevars look like this:
CXX14FLAGS=-O3 -mtune=native
CXX14FLAGS += -arch x86_64 -ftemplate-depth-256 -Wno-unused-local-typedefs -Wno-unused-function
FC = /usr/local/bin/gfortran
FLIBS = -L/usr/local/lib/gcc/10 -L/usr/local/lib -lgfortran -lquadmath -lm
i.e., no -march=native flag.

Thanks! I’ll ping you when I’ve got something drafted

I keep seeing non-zero exit status for pkgbuild and callr.
For rstan it says unpacked and md5 sums checked.
I googled non-zero status and found that that means error and it wasnt installed?
Also then I tried installing rethinking and got this (I have R version 4.0.2)
Installing package into �C:/Users/AACH4770/Documents/R/win-library/3.4�
(as �lib� is unspecified)
Warning in install.packages :
package ‘rethinking’ is not available (for R version 3.4.3)
Once rstan is installed you can install rethinking,
install.packages(c("coda","mvtnorm","devtools","loo","dagitty"))
devtools::install_github("rmcelreath/rethinking")
I don’t think that you’re on R4.0.2. This error:
package ‘rethinking’ is not available (for R version 3.4.3)
Implies that RStudio is using R 3.4.3. If you have have 4.0.2 installed, you can follow this guide to get RStudio to use it: https://support.rstudio.com/hc/en-us/articles/200486138-Changing-R-versions-for-RStudio-desktop
I realize how that sounds but…
Just realized I have 4.0.2 but I havent uninstalled prev. versions… Will try.
Just realized I have 4.0.2 but I havent uninstalled prev. versions… Will try.
After that, can you run:
devtools::session_info()
If it throws an error about devtools not being installed, then run:
install.packages("devtools")
and try again
This fixed my issues with rstan on windows 10, thanks a lot. Can you explain what this is?
The error:
Error in withr::set_makevars(new, path, state, assignment = assignment) :
Multiple results for CXX14FLAGS found, something is wrong.FALSE
Is caused by having multiple CXX14FLAGS lines in the Makevars.win file. The command I posted overwrote the Makevars file leaving only one line
