using rstan library via R scipting nodes?

I’m having trouble using R scripting nodes to run the R library rstan. This library runs a c++ compiler to compile “stan” files (mc-stan.org), executes the compiled files, and allows manipulation of the results. I’m running KNIME 3.5.2, R 3.4.3 and rstan 2.17.3 on Windows.

When I use Rstudio to run my local R install and compile a stan file, compile works but I do get a warning message that seemingly cannot be turned off:

^
:0:0: note: this is the location of the previous definition

When I run the same commands within KNIME, the result is:
Error: ‘C:/Program’ not found

In both cases, the file parser runs at the beginning of the compile command and returns the same warnings.

Any ideas?

Hi Kari,

Can you please confirm whether you are using the same R installation from both KNIME and Rstudio?

Cheers,
Roland

Yes, they are.

RStudio is running [Default] [64-bit] C:\Program Files\R\R-3.4.3
Knimes Path to R home is C:\Program Files\R\R-3.4.3

Hi @KariOlson,

Regarding the warnings in general, I found this: https://github.com/stan-dev/rstan/issues/372. It seems that this is a known issue that shouldn’t affect execution.

Can you please check in your knime.log if there is some more information? Do you get any results back or just the error?

Cheers,
Roland

I’ve seen the github post and had the same issue as the last poster - the “fix” to shut up the warning causes a compiler error (which is worse than the warning).

In Rstudio, I do get results (a compiled model that I can sample), but within Knime the block fails with the previously noted error.

Here’s what I see in the Knime log:
