[R-SIG-Mac] making R64 the default gui

[Airey, David C]

Dear list,

I have a bit more RAM now and want to make R64 the default GUI.

What is the best way to do this?

The simplest way outside the terminal is to get info on a file and make an application the default for a particular extension, like .r or .rdata, etc. But for some reason this doesn't work with the R.app and R64.app distributed. R64 doesn't stick, and reverts to R in the Get Info window.

Can someone (1) explain this behavior, and (2) provide alternative instructions?

Thank you.
