You don't describe the variable holding those labels. If it is a factor with
the levels in the desired order then it should display properly.
Duncan,
Apologies; I did not know what supporting information to provide.
It's a factor in the data frame, but obviously not in the desired order.
To get that, try something like this (simplified to fewer levels, because
I'm lazy):
# Set the levels in the desired order:
x <- factor(x, levels=c("SC", "SC-1", "SC-2", "SC-100"))
Here's an example of the command:
xyplot(TDS ~ SO4 | site, data = snow.cast, main = 'TDS in Snow Canyon
Creek', ylab = 'Concentration (mg/L)', xlab = 'Sulfate (mg/L)')
If I correctly understand, I'd first assign the desired sequence to a
variable (x in your example above), the specify that variable as the
conditioning factor in the formula; e.g,,
xyplot(TDS ~ SO4 | x, data = snow.cast, main = 'TDS in Snow Canyon
Creek', ylab = 'Concentration (mg/L)', xlab = 'Sulfate (mg/L)')
Thanks very much for the insight!
Happy New Year,
Rich
