...tion(fr, link)) which is called from Sys.junction(). I have run Sys.junction inside the RStudio debugger and I checked that the 'U:/packrat5/packrat/lib-R/base' could be accessed via the windows file explorer before the .Internal(mkjunction(fr, link)) call is made. Looking at the code for do_mkjunction(), the warning looks to be thrown based on the return status from DeviceIoControl. I setup a project on the C: drive and tried the same packrat::init() code. The call to .Internal(mkjunction(fr, link)) did not produce an error. I would appreciate any help you can provide on this issue. Thanks...
