I was sure it was simple. That was exactly what I wanted.
I should have clarified that I was looking for a box-plot.
Thanks to all who responed.

Sandy,
You can re-order a factor with
df$Eyeball<-factor(df$Eyeball, levels=c("Normal", "Mild", "
I'm not really clear on what you want here. Are you talking about plotting
multiple data points for each value ? In that case something like boxplot
might be what you want. Otherwise if you just wish to plot a data point for
each occurance of Normal etc then this will work but I'm not sure h

Hi
I'm sure this question has been asked before but I can't find it in the

I have a data frame which includes interval and ordered nominal results.
It looks something like
"Measured" "Eyeball"
46.5 Normal
43.5 Mild
56.2 Normal
41.
Sandy,
You can re-order a factor with
df$Eyeball<-factor(df$Eyeball, levels=c("Normal", "Mild", "Moderate",
"Severe"), ordered=T)
(assuming df is your data frame and that you want an _ordered_ factor;
the latter is not essential to your plots)
Incidentally, "NULL" isn't a particularly friendly
