I used the plot function to create some graphs but wanted to add soem
restrictions. A set of warning were produced even though the plot worked fine.
Can these warnings be cleaned up? Here is an example:
***************************************

plot(xx$month, xx$log10RR, xlab="", ylab="", type='n', xlim=c(0,60),

ylim=c(-0.2,0.3),tick=F, labels=F)
Warning messages:
1: In plot.window(...) : "tick" is not a graphical parameter
2: In plot.window(...) : "labels" is not a graphical parameter
3: In plot.xy(xy, type, ...) : "tick" is not a graphical parameter
4: In plot.xy(xy, type, ...) : "labels" is not a graphical parameter
5: In box(...) : "tick" is not a graphical parameter
6: In box(...) : "labels" is not a graphical parameter
7: In title(...) : "tick" is not a graphical parameter
8: In title(...) : "labels" is not a graphical parameter

# expect warning that tick and labels are non-graphical parameters but it

works

points(xx$month, xx$log10RR, col='red')
lines(xx$month, xx$log10RR, col='red')
