Argument for fwrite to set the file 'Owner' on Windows

[msgoussi]

Is it possible to add a creator argument in fwrite that controls the owner property in Details Tab in Windows?

[MichaelChirico]

AFAICT the way to do so is with a command line utility 'icacls', e.g.

https://github.com/zerland/MAGMA_Celltyping/blob/8cb235fb495a467fb825819a76b2f154d3840146/R/set_permissions.R#L19-L23

Why should {data.table} own this logic? It seems more natural to me that another package/wrapper would simply follow up the fwrite():

fwrite(table, file)
set_acls(file)

when i use openxlsx::write.xlsx, there is a argument called "creator".
Thanks in advance

AFAICT they do so relying on some code in the C++ API. It makes more sense for a package like {openxlsx} to be deeply integrated with Windows. I think {data.table} should be more platform-agnostic.

Completely agree. A good workaround could be to use wsl in windows and run something like this

sudo -u newOwner R
