[R-sig-Geo] colorkey print order is incorrect??

[Jim Burke]

Question. When I use the code below to print
a list of values to the right of my graph,
the colorkey list appears unusual.  At the top
the list of percentages tops out at 90.87%
instead of the expected 100%. The 100% appears
at the bottom below the lowest percent 14.29%.

The numbers of tx3_sp CK_PCT are read in as follows.
ID is the PCT and CK_PCT is what's plotted.

Is there any way to move the 100% to the top
when the colorkey legend prints?

    spplot(tx3_sp, c("CK_PCT"),
        names.attr = c("Carol Kent 2008"),
        colorkey=list(height=1.0, width=0.6),
        main = "HD102 - Carol Kent",
        sp.layout = list("sp.text",coordinates(tx3_sp),
        as.character(tx3_sp$PCT,cex = .02),
        as.table = TRUE))

See the attached jpg file. I hope this goes through.

Forgive my dumb question as I am new to R. I like
R after reading the NYTIMES article last week;
"Data Analysts Mesermized by Power of R". Query
the NYTIMES for this. And read the "Are U Ready
for R" article with its comments as well.

Thanks,
Jim Burke
