Hello,
I am new to Stan and am trying to get Stan working before a workshop I plan to attend.
I am following along with installation, RStan Getting Started · stan-dev/rstan Wiki · GitHub all seems well, until I try and run the sample code in which I get:
install.packages(“rstan”, repos = “https://cloud.r-project.org/”, dependencies = TRUE)

rstan (Version 2.18.2, 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)
For improved execution time, we recommend calling
Sys.setenv(LOCAL_CPPFLAGS = ‘-march=native’)
although this causes Stan to throw an error on a few processors.
rstan_options(auto_write = TRUE)
