The documentation for tempdir() and tempfile() on R-2.2.1 for Windows
says that "Both will use backslash as the path separator", but in
practice I see a forward slash:
> tempdir()
[1] "C:\\DOCUME~1\\ADMINI~1\\LOCALS~1\\Temp/RtmpGqB7ob"
> tempfile()
[1]
"C:\\DOCUME~1\\ADMINI~1\\LOCALS~1\\Temp/RtmpGqB7ob\\file6df11649"
This causes problems when the string is passed as a parameter to a
Windows program that accepts only backslash as a path separator.
For example, fix() appears to pass the tempfile() string to the
editor program and my preferred editor (KEDIT) does not accept it:
I get an error message "Invalid fileid" from KEDIT and a warning from
fix() "Warning message: editor ran but returned error status in:
edit(name, file, title, editor)". I can work around this with
fix(object,file=normalizePath(tempfile())), but I would rather have
tempfile() return a normalized path in the first place.
