i got same error:
> my.dat = addm_preprocess(choice.dat = addm_data_choice,
+ eye.dat = addm_data_eye,
+ timestep = 10,
+ rtbinsize = 100)
Error in setkeyv(x, cols, verbose = verbose, physical = physical) :
x is not a data.table

EDIT:
i found error code:
eye$fixdur = timestep * round(eye$fixdur/timestep)
rts = eye %>% group_by(id) %>% summarize(rt = sum(fixdur))
setkey(rts,id)
choice = choice %>% select(-rt)
choice = choice[rts]
setkey(rts,id) return error:
> rts
# A tibble: 1 x 2
id rt
* <dbl> <dbl>
1 0 0
> setkey(rts,id)
Error in setkeyv(x, cols, verbose = verbose, physical = physical) :
x is not a data.table

It looks like you're providing a tibble when a data.table is expected.
You should be able to convert the object with as.data.table.
Alternatively you could also use dtyplyr for unified tibble/data.table
objects. github.com/tidyverse/dtplyr
