Dear Gang Chen;
The .Rprofile is loaded from the startup directory. Terminal.app will
start up in /Applications/ while your R.app session appears to be
starting in a different directory. (We don't know what your startup
directories are.) I'm using R.app in /Applications/ so my .Rprofile
has the same effect regardless of whether I run from R.app or from a
bash console.
See this portion of the Mac-FAQ:
http://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html#The-current-and-startup-working-directories
See ?Startup for more specifics that are generic to all R versions:

The only reason that *should* happen is if there's an .Rprofile in
the directory you're in when you start R.
Where *exactly* is the .Rprofile file you want loaded, what
directory are you starting from, and what does R say is the user's
home directory? Did you make *any* changes to Rprofile.site, or
Renviron?
What is the output from Sys.getenv() in gui and cli, and do they
differ?
They might differ even if the default directories are the same (as
they are on my setup). I have a somewhat older version on this laptop
but there are names of environment variables that are not present in
both directions:
I ran AppEnv <- dput( Sys.getenv() ) on my R.app session and then ran
the corresponding command on a Terminal console session:
These are the difference (on a R 2.15.2 setup):
> AppEnv[ !names(AppEnv) %in% names(conEnv)]
R_GUI_APP_REVISION R_GUI_APP_VERSION
"6435" "1.53"
> names( conEnv[ !names(conEnv) %in% names(AppEnv)] ) # i.e. missing
in the GUI installation
[1] "COLUMNS" "DYLD_LIBRARY_PATH"
"GDK_USE_XFT" "INFOPATH"
[5] "LINES" "MANPATH"
"PERL5LIB" "PWD"
[9] "SHLVL" "TERM"
"TERM_PROGRAM" "TERM_PROGRAM_VERSION"
[13] "XDG_CACHE_HOME" "XDG_CONFIG_DIRS"
"XDG_CONFIG_HOME" "XDG_DATA_DIRS"
[17] "XDG_DATA_HOME"
If there are further points of discussion they should be thrashed
out (with greater details about sessionInfo() and startup settings),
over on the R-MAC-SIG mailing list.

When R starts in GUI (e.g., /Applications/R.app/Contents/MacOS/R) on
my Mac OS X 10.7.5, the startup configuration in .Rprofile works
fine.
However, when R starts on the terminal (e.g.,
/Library/Frameworks/R.framework/Resources/bin/R), it does not work at
all. What could be the reason for the failure?
Thanks,
