Subject: [Rd] Feature request: make file.exists interruptable
Message-ID: <YQBPR0101MB15856467D2E279C9AD0ACBA9E82B0@YQBPR0101MB1585.CANPRD01.PROD.OUTLOOK.COM>

Hi R developers,

On slow file systems with large lists of files, file.exists can take a long time to run. It would be nice if users could interrupt this function. I think it would be simple to add:

https://svn.r-project.org/R/trunk/src/main/platform.c,

at line 1373, add "R_CheckUserInterrupt();" perhaps every some number of iterations if performance is a concern here.

Thanks,

Chris
