Cannot find stan model directory #21
Description
I tried the following code (from the manual) on my system:
set.seed(42)
s <- sim_dfa(num_trends = 1, num_years = 20, num_ts = 3)
obs <- c(s$y_sim[1, ], s$y_sim[2, ], s$y_sim[3, ])
long <- data.frame("obs" = obs, "ts" = sort(rep(1:3, 20)), "time" = rep(1:20, 3))
m <- fit_dfa(y = long, iter = 50, chains = 1, data_shape = "long", sample= FALSE)
and received the following error
Error in dirname(file) : a character vector argument expected
error in specifying arguments; sampling not done
The error occurs at the line
mod <- do.call(sampling, sampling_args)
I suspect this may be an issue with cross-platform compatibility/differing locations for compiled Stan models. My system details are as follows:
