[R] using par funtions in bargraph.CI()

[maxa0006 at umn.edu]

I'm trying to create a bargraph of means with standard error bars using the 
function bargraph.CI (in the sciplot package). Like this:

bargraph.CI(x.factor, response,data,xlab, ylab, par(family="serif"),font=11)

However, an error message comes up when I try to use the par funtion. Does 
the character font/style need to be changed in a different way for this 
kind of plot? Or am I misusing the par function?

Thanks!
