R help - Feb 2013 - Controlling Order of Panels in Lattice Trellis Plots

With multiple panels in a lattice trellis plot the sequence is, for
example, 1, 10, 11, 12, 2, 3, 4. I want the sequence to be 1, 2, 3, 4, 10,
11, 12.

   Reading ?strip.default and the appropriate section in the Lattice book
I'm
not seeing how to specify the 'human' numeric order rather than the
computer
numeric order.

   A pointer will be appreciated.

TIA,

Rich

It appears these may be factors. No much in the way of code can be offered since
you have provided none of hte requested details.

Many pointers have been offered, but you have refused to heed them.

As you appear not to know, or at least have not stated, **what** you
want to do, how can you expect anyone to tell you **how** to do it?

Cheers,
Bert

Without knowing what you're trying to do, I can't be sure, but I think
this pointer could give you an idea:

> cc <- 13:1
> levels(as.factor(cc))
 [1] "1"  "2"  "3"  "4"  "5" 
"6"  "7"  "8"  "9"  "10"
"11" "12" "13"
> levels(as.factor(as.character(cc)))
 [1] "1"  "10" "11" "12" "13"
"2"  "3"  "4"  "5"  "6" 
"7"  "8"  "9"

Any sorting of input text file do not change factor levels ordering in R which
is by default alphabetic.

Do not guess how the language works, learn the rules from documentation and help
pages.

If you learned some foreign language you need to know some vocabulary and
grammar to express understandable thoughts. And mostly people are more
intelligent than computers when dealing with incomplete and twisted sentences.
