[R] R help - howto suppress chm help and use text/latex help?

[Tsunhin John Wong]

Dear R Users,

I've installed R with the chm option, but eventually I found I am more
used to the normal way of latex help.
Is there any argument to suppress chm help by default when starting R?
So that I don't have to type something like >help(rle,chmhelp=NULL)

I know the last resort would be to reinstall R.
Thanks in advance!
