Hi,
We are using a virtual desktop infrastructure (VDI) at company. I just installed Rstan on my VDI, and tried some tests on the installation. The version of R is 3.5.0, Rstan is 2.17.3, Rtools is 3.3. All the installations are done on the server that I don’t have privilege of administrator. It seems that the installation didn’t add path of rtools to the system path environment. system('g++ -v')
returns nothing, no error or any message. I tried the 8school example, and a simple Bernoulli example as below:
// test.stan
data {
int<lower = 0> N;
int<lower = 0, upper = 1> y[N];
}
parameters {
real<lower = 0, upper = 1> p;
}
model {
p ~ beta(1, 2);
y ~ bernoulli(p);
}
Both models compiled with no error, but there is a warning message always appears:
" Warning message:
In if (nchar(CXX) > 0) return(TRUE) :
the condition has length > 1 and only the first element will be used"
rstan:::get_CXX()
returns “C:/FAST/RTools/3.3/mingw_/bin/g++”.
I never went into such issue with my personal laptop.
Do you know what might be the cause for this warning message?
Thanks!
