Can't load *.dat files after update

[ProfessorPeregrine]

Previously, my app would load text files with a .dat extension (usually they would be tab-delimited). Now it says " Ooops Format not supported"

Is there a way to add this functionality back? There are many legacy files that loaded just fine that I will have to change the extension on now if not.

Thanks again for an amazing package!

Hello,
It seems that package rio no longer support .dat files, this produce an error :

readr::write_delim(mtcars, file = "mtcars.dat")
rio::import(file = "mtcars.dat")

if you want to be able to import .dat files with datamods you can still specify the function to use manually for this specific extension :

imported <- import_file_server(
  id = "myid",
  read_fns = list(
    dat = function(file) {
      readr::read_delim(file = file)
    }
  )
)

Thanks Victor. How would this work with modal import? I see that import_modal() doesn’t have the read_fns parameter. From my app: #Data Import ########################################## observeEvent(input$launch_modal, { req(input$from) import_modal( id = "modal_import", from = input$from, title = "Import data to be used in application" ) }) imported <- import_server("modal_import", return_class = "data.frame") Steven Ouellette, MS, CMC® President <http://www.roi-ally.com/> The ROI Alliance, LLC From: Victor Perrier ***@***.***> Sent: Wednesday, November 8, 2023 3:59 AM To: dreamRs/datamods ***@***.***> Cc: ProfessorPeregrine ***@***.***>; Author ***@***.***> Subject: Re: [dreamRs/datamods] Can't load *.dat files after update (Issue #79) Hello, It seems that package rio <https://github.com/gesistsa/rio> no longer support .dat files, this produce an error : readr::write_delim(mtcars, file = "mtcars.dat") rio::import(file = "mtcars.dat") if you want to be able to import .dat files with datamods you can still specify the function to use manually for this specific extension : imported <- import_file_server( id = "myid", read_fns = list( dat = function(file) { readr::read_delim(file = file) } ) ) Victor — Reply to this email directly, view it on GitHub <#79 (comment)> , or unsubscribe <https://github.com/notifications/unsubscribe-auth/AV6KQR4NP4YXZVWJ2NOJKNLYDNQXZAVCNFSM6AAAAAA6YM24AOVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMYTQMBRGY2DIMRSHA> .

Be sure to use latest version, import_server() should have a read_fns argument.

Aha, got it! Thanks!

Hmm, this change doesn’t seem to allow single-column text files to be loaded, even though readr has no problem with it. Files with more than one column delimted by tabs seem to work fine. The attached file gives the “oops” message.

Seems to be a readr error, for single column file you have to explicitly set delim = " ", e.g. :

readr::write_delim(mtcars[, 1, drop = FALSE], file = "mtcars1.dat")

readr::read_delim(file = "mtcars1.dat")
# Error: Could not guess the delimiter.
# 
# Use `vroom(delim =)` to specify one explicitly.

readr::read_delim(file = "mtcars1.dat", delim = " ")

@pvictor @ProfessorPeregrine Sorry for the breaking change. Will fix this here gesistsa/rio#430 .
