[R] lattice panel.linejoin type question

Hello R Users!

I'm trying to use the panel.linejoin function to draw points and lines (type="o") but it wouldn't do it. Modifying the panel.linejoin function as such (adding type argument to the panel.lines call).  

*original*

        panel.lines(vals[xx], yy, col = col.line, lty = lty, 
            lwd = lwd, ...)

*modified

panel.lines(vals[xx], yy, col = col.line, lty = lty, lwd = lwd, type, ...)

Then passing the type="o" in the panel.linejoin call as such works. xyplot(

	...
	,panel.groups=function(x,y,subscripts,...) {
 		panel.linejoin(x,y,fun=mean,type="o",...)
	}

)

However, if I don't add the "type" in the panel.lines call, I get a "formal argument "type" matched by multiple actual arguments" Error.

It seems like overkill to redefine panel.lines, is there a simpler way?

R 2.4.1 Windows XP
Lattice 0.14-16

Sam
