[R] Suppressing internal grid in filled.contour

[Jonathan Greenberg]

Ok, I've placed the input files and the PDF on a website (I apologize 
for attaching the PDF -- the readme guide for this listserv indicated 
that PDFs were fine):

http://www.cstars.ucdavis.edu/~jongreen/temp/

The full suite of commands I used are:

tahoecontourdata<-read.csv("tahoedata02.csv",header=TRUE)
x=tahoecontourdata$Elevation_Bin
y=tahoecontourdata$PRR
z=tahoecontourdata$MaxStems
tahoelinedata<-read.csv("tahoelines02.csv",header=TRUE)
xline=tahoelinedata$Elevation
yline=tahoelinedata$PRR
filled.contour(interp(x,y,z,duplicate="strip",xo=seq(1800,3200,length=57),yo=seq(120,280,length=65)),col=grey.colors(33,start=0,end=1,gamma=1),nlevels=33,zlim=0:650,plot.axes={axis(1);axis(2);points(xline,yline,type="l")})

As you can see in the PDF, there is a faint internal grid that I can't 
seem to disable.

Thanks again!
