Infinite Error Printing - sh: findstr: command not found

[ghost]

I am running ctStanFit to receive a Bayesian estimation via Stan’s NUTS sampler. An error message is infinite loop printing while doing so. This doesn’t seem to be interfering with the underlying computation as the function appears to run to completion (albeit probably slower). The error is sh: findstr: command not found

From a quick search of the codebase, there doesn't appear to be many instances of the findstr function. Just here and here.

As brought up by Jonah here, the below code does NOT produce the same error pattern

library(rstan)
code <- "
parameters {
  real x; 
} 
model {
  x ~ normal(0, 1);
} 
"
fit <- stan(model_code = code)

Any help is appreciated. Thanks in advance!

Are you fitting with the argument plot=TRUE or plot = some positive integer? What operating system?

Mac OS. This is the full function call

ctStanFit( datalong      = cswim1,
                 ctstanmodel   = m1,
                 iter          = 2
                 optimize = FALSE,
                 intoverstates = TRUE,
                 algorithm = "NUTS",
                 nopriors = FALSE,
                 chains        = 4,
                 cores         = 4,
                 fit = TRUE,
                 plot=TRUE
              )

Ok. I probably have to find an alternative to that function if it's not generally available on macOS. To avoid the error just disable the plot output when using sampling - with optimisation it will still work fine.

Will do. Thanks for the help!
