Duplicate names error with example in vignette

[zuhadhai]

Hi, I'm having a bit of trouble getting the first example in the vignette to work for me. Specifically, I get a "Duplicate names not allowed in 'data'." error. I'm using cmdstan-2.31.0, if that helps. I also get
I've attached the code and error output below.

Hi Zuhad -

I am releasing a big update of the package in a bit so the current version is a bit out of sync. You can install the development version with the following command:

remotes::install_github("saudiwin/idealstan", ref="develop")

I just tested the above vignette code and it works fine. If you find any other bugs though please do let me know, thanks.
