Warning issued when setting temp folder #34

Hi,

Thank you so much for creating an "updated" version of ff.

I have started using Andromeda but when I set the temp folder to my secondary HDD, I get the following Warning message. I think this should not be an issue as the .sqlite file is created successfully in that folder, but I was wondering if it could generate any problems downstream (like if Andromeda needs to create subdirectories or something like that...).

I guess adding a showWarnings = FALSE to the dir.create would avoid this warning message.

Best,

> options(andromedaTempFolder = "D:/andromeda_temp/")
> andr = andromeda(data = df)
Warning message:
In dir.create(tempFolder, recursive = TRUE) :
  'D:\andromeda_temp' already exists

Hi @eggrandio, Thanks for the report. Will you try the "arrow_S4" branch and see if the warning still occurs? devtools::install_github("OHDSI/Andromeda", "arrow_S4")
