[R-SIG-Mac]How to start browser from within R

[Jun Tan]

Hello, Everyone:
I downloaded a R for MacOSX(Darwin/X11). Everythin works well except the
help system. I wanted to show the help information in a browser and I knew
that the command "open" can be used to start the browser. However when I
tried to start browser in R, nothing happened. The command I used was:
system("open $HOME/.R/doc/html/index.html")
Is there anyone can give me some advices? Thanks.
