R help - Oct 2009 - How to start R in mac with the current directory as the current working directory?

Hi,

I installed R on mac (see below). When I start it from a terminal by
the following command, the current working directory is always '~' no
matter where my current directory is in the terminal. I'm wondering if
there is a way to make the gui R on mac inherent the current directory
from the terminal.

/Applications/R.app/Contents/MacOS/R

Regards,
Peng

Look in the R > Preferences >Startup dialog under the "Initial
working
directory" section. You'll see you can run this from the command line  
in order to open R.app within a given directory:

$ open -a R.app <dir-or-file>

So, to open in the current directory, just type:

$ open -a R.app .

You can make an alias for this and set it in your .bash_profile in  
order to make your life easier, maybe:

alias r="open -a R.app ."

Small r so it doesn't interfere with /usr/bin/R

Hope that helps,

-steve
