New to R - rookie question. 
I'm a mechanical engineer and enjoying using R to make high quality graphs. 

I've searched. 

I want to put text notation on graph plot areas and have the text background
"box" white to cover over the grid lines. 

my command so far.... 
text(15,5200,"Air Flow",cex=.8,col="blue", background="white") # this
doesn't work... 

I've tried bg="white", background color="white" and a number of other
attempts. 

The text is getting placed on the chart where I want it. 

Thanks, 
-Henry

How about using the legend function ...

plot(rnorm(100))
legend(60,2,"100 Random Normal Draws",cex=.8,text.col="blue",
box.col="red",bg="yellow")

You can customize my effort to fit your specific needs

Hi Henry,
have a look at the boxed.labels function in the plotrix package.

An alternative is the shadowtext function in the TeachingDemos package.
