How to get started with the glba R-package? I am struggling with getting started using the glba package in R.

Often, the program will not fit the data at all. It immediately converges, but not really, and then instead of estimating it gives the starting values that I gave it, or it generates absurd values, such as negative non-decision times.

I tried to fit the data that is given as an example (bh08) and it worked great, however, with my own data that seemed superficially at least very similar (the RT distributions were in the same ballpark, and with a similar distribution shape) it did not work (converged immediately).  I started with the suggested starting values, but also changed them. 

Any smart advice?  

(I guess RT should be in seconds and accuracy is a 1:0 variable.  By the way, the program worked and did not stop when RT was in milliseconds, but the estimates were bizarre).
It appears as if the problem was caused by pre-processing using (the amazing) tidyverse package.  When I (a) wrote the dataframe as a .csv file and then uploaded it, the LBA worked (in most subjects) nicely, converged quickly, and yielded sensible estimates.

Thank you!
