Is it possible to open a specific file in the HTML browser like help(htmlhelp=TRUE) does?

Ok, so here is something that works for windows and unix
openBrowser <- function (query) 
{
    OST <- .Platform$OS.type
    if (OST == "windows") {
        shell.exec(query)
    }
    else if (OST == "unix") {
        if (is.null(getOption("browser"))) 
            stop("options(\"browser\") not set")
        browser <- getOption("browser")
        system(paste(browser, " -remote \"openURL(", query, ")\"
	2>/dev/null || ", 
            browser, " ", query, " &", sep = ""))
    }
    else {
        msg <- paste("don't know how to open the browser on", 
            OST)
        stop(msg)
    }
    return(NULL)
}

Henrik,

I have actually just started a function in the report writing library
I'm working on which does this.  All I really did was rip off code from
help.start.  The key part is the system call at the bottom of the
function.  Problem is, this is not portable (as others have mentioned).
If you come across a better way of doing this, let me know.

Dear all/anyone, after generating a HTML file "result.html" from within [R],
I would like to open the default HTML browser (like help.start() does) to
show the file. Is it possible to do this (without trying to do a system
dependent search for possible browsers)? I browsed the source of package
'base' (R v1.4.1 WinMe) and I found the following in help():

   .Internal(show.help.item(file, 1, ""))

but I couldn't get it to load "result.html", which is in the current
directory and also, since it is not documented I don't know if this is a
cross-platform function or even safe to use.

Suggestions?
