    Re: R help

    I am going to avoid getting myself into the middle of most of this,

    (I left my flame proof pants at home and I've already managed to get sucked into a discussion of EMACS v Vim in this thread.)

    but I should not that help.start() is a local function. It does not (on my Linux box) reach out to R on the interwebs. It will work just fine locally. I show it as being located at:

    http://127.0.0.1:15801/doc/html/index.html

    IIRC, Newish versions of R include an embedded web-server. I don't know which web-server and it only starts if you do the help.start(), AFAIK.

    Sorry, I just couldn't help myself. I've been teasing EMACS users for 20+ years now.

    What I've appreciated from this thread is that out of ignorance I never bothered to look up the local R documentation, so I've learned something new. Long ago I had downloaded several PDFs and I have basically used them and the "?" command (mostly the "?" command, really). I didn't even know about help.start().

    Yeah - well if it makes you feel any better, I tend to do the exact same thing -- read the PDF files that I have stored on my computer and use ?, and I knew about help.start(). For some reason, I never got into the habit of using it.

    This is one of the big reasons that I use rkward, the access to the HTML help files is so direct and easy.

    Re: R help

    One of the help feature that is included in R for OS X that for some reason isn't done the same way on R for Windows (sorry, don't have it installed on my latest install of Ubuntu yet for comparison) is the 'Vignettes' under the Help menu in the R gui. Basically it opens up a menu window with a series of short pdfs on various topics - and you can get others from CRAN, such as HSAUR (Handbook of Statistical Analysis Under R), for example. You can preview each one in a small viewer window, or open them fully in Adobe Acrobat or whatever your preferred PDF viewer is. I was really disappointed to find this particular aspect of the R gui didn't make it over to the Windows port - from what I've heard, its a Mac-only thing for some reason.

    Re: R help

    I did not know about HSAUR -- THANKS!

    R is an enigmatic tool. There should be a sticky full of tricks and tips.

    gunksta,

    I agree. I really like this page:
    http://pj.freefaculty.org/R/Rtips.html
    It doesn't give much intuition or structured teaching. But sometimes tips and trick are good enough by themselves!
