I would like use "reorder" in the "dotplot" function. I want the
dots in
the increasing order. I know how to do it using "dotchart".
The Posting Guide also suggests that you offer code that constructs a
dummy dataset if you cannot provide a representative real dataset.
With the barley dataset you can see the effects of sorting a factor
variable with this code:
> dotplot(variety ~ yield | year * site, data=barley)
>
> str(barley)
'data.frame': 120 obs. of 4 variables:
$ yield : num 27 48.9 27.4 39.9 33 ...
$ variety: Factor w/ 10 levels "Svansota","No. 462",..: 3 3 3 3 3 3
7 7 7 7 ...
$ year : Factor w/ 2 levels "1932","1931": 2 2 2 2 2 2 2 2 2 2 ...
$ site : Factor w/ 6 levels "Grand Rapids",..: 3 6 4 5 1 2 3 6 4
5 ...

"Morris" "Crookston" "Waseca"

I would appreciate help. Also I could not easily find a method to
post data
when I seek help in the posting guide.
I was under the impression that files with extension .txt would pass
the server filter. I am attaching two copies of the same file, one
with .txt and the other with .csv as extensions. My experience tells
me that only the .txt file will pass.
