[R] xYplot error

[Kang Min]

Hi Frank,

Thanks for the suggestion. using numericScale() does work for Dotplot,
but there're still a few issues:

1. My factor names are Plot A, PF, MSF, and YSF, so numericScale turns
that into 3, 2, 1, 4 and the x-axis is plotted 1, 2, 3, 4. Is there
any way I can retain the same order on the graph?

2. I can't get the error bars displayed even after using
method="bars", only the mean, lower and upper bounds of the data as
points.

This the line I used: Dotplot(cbind(mort, mort + stand, mort - stand)
~ numericScale(site) | type, data = mort, method="bands")

Thanks for your help.

KM
