Problem with LaTeX table: ErrorL subscription out of bounds

[storopoli]

There is an error when generating LaTeX table in shinystan. I've run the model with brms, but this happens when also converting brms code and data to rstan:

library(brms)
library(rstan)
library(shinystan) 

fit <- brm(
    bf(mpg ~ 1 + (1 | cyl) + hp + wt, decomp = "QR"),
    data = mtcars,
    family = gaussian
)

code <- stancode(fit)  
dat <- standata(fit)
fit2 <- stan(model_code = code, data = dat) 
launch_shinystan(fit2) # or `brmsfit` fit

The error only happens when I select Quantile: 97.5%, see pics below:

@VeenDuco do you know where in the code this might be?

[VeenDuco]

Hey, this should be here and here. My guess would be that we do not name the slots of the summary output correctly. Although the code does seem to refer to 97.5%, which you also get in the summary table.

In version 3.0 I don't get this error, see below. Will check now for the CRAN version.

I also don't get an error with shinystan 2.5. @storopoli could you post your session information?
