[R] Problem running stan interactively

[Tobias Fellinger]

Hi,


I try to run a stan model in R 4.0.2 and the session crashes if I run the code interactively (sourcing from an interactive session or from Rstudio) but runs fine if run with Rscript or R -e 'source("rstan_test.R")' . I don't really know where to begin to debug this.

I'm not sure if this is due to the setup on my machine or if this is a bug in either the packaging on Debian, the rstan package or R itself, so I'm posting it here in the most general mailinglist.


For now just running the model in a non-interactive session is a workaround. R and stan code and sessionInfo below.


All the best and thanks in advance, Tobias


==== rstan_test.R ====
library(rstan)


schools_dat <- list(J = 8,

y = c(28, 8, -3, 7, -1, 1, 18, 12),

sigma = c(15, 10, 16, 11, 9, 11, 10, 18))


fit <- stan(file = 'schools.stan', data = schools_dat)


message("done")

==== schools.stan ====

// saved as schools.stan

data {

int<lower=0> J; // number of schools

real y[J]; // estimated treatment effects

real<lower=0> sigma[J]; // standard error of effect estimates

}

parameters {

real mu; // population treatment effect

real<lower=0> tau; // standard deviation in treatment effects

vector[J] eta; // unscaled deviation from mu by school

}

transformed parameters {

vector[J] theta = mu + tau * eta; // school treatment effects

}

model {

target += normal_lpdf(eta | 0, 1); // prior log-density

target += normal_lpdf(y | theta, sigma); // log-likelihood

}
