Change of results when using tb() in grouped freq()

[Crismoc]

After getting results from a grouped freq(), I would like to put them in an object with tibble or data.frame format. When using tb() the results are transformed in what might be unintended behavior:

library(summarytools)
library(dplyr)

#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':

  freq(diseased)

Is there a way to transform the same results to a tibble or data.frame?

[dcomtois]

Could you pls show what would be the desired resulting df?

I would expect to get something like this:

library(summarytools)
library(dplyr)

tobacco |> 
  group_by(smoker) |> 
  reframe(
    level = names(table(diseased)),
    Freq = table(diseased),
    `% Valid` = prop.table(table(diseased)))
#> # A tibble: 4 × 4
#>   smoker level Freq        `% Valid`  
#>   <fct>  <chr> <table[1d]> <table[1d]>
#> 1 Yes    Yes   125         0.4194631  
#> 2 Yes    No    173         0.5805369  
#> 3 No     Yes    99         0.1410256  
#> 4 No     No    603         0.8589744

I see what you mean. The proportions are recalculated to take into account both groups, and it can create confusion. Aside from better documenting this, I think an additional parameter is in order. That way the user can decide whether to recalculate proportions or not. Thank you for pointing it out.
