Inconsistent results with fmutate

[romu545]

Greetings. I have the following problem with fmutate. When using arguments other than "all" for a row-0 dataframe, the function removes the 'names' attribute. What do you recommend? I need the names to be preserved both for cases in which records exist and for those in which they do not. Thanks, I'll be waiting!

Example: `

CON COLLAPSE

iris |> fsubset(Petal.Length > 100) |> fmutate("variable" = Species, .keep = "none") |> attributes()

CON DPLYR

iris |> fsubset(Petal.Length > 100) |> mutate("variable" = Species, .keep = "none") |> attributes() `

Thanks. This is a bit difficult to fix the way fmutate() is currently constructed, basically the .keep argument calls a function which also removes empty/NULL columns. However, you can use function fcompute() instead here to get the desired result.

Gracias, Ha sido una limitante que algunas de las funciones de collapse generen error con 'Dataframes' con cero filas o vacíos.
