R help - Dec 2005 - panel order in xyplot

Hi all,

 

I have a question concerning xyplot. My data is a data.frame looking like that:

 

In the first column I have numbers from 0 to 23 (hours of a day), the second
column contains the name of a weekday (Day as factor) and the third column
contains the number I am interested in. So as an example, the first five rows
look like that:

 

    Hour Day Freq

1     0  Mo    23

2     1  Mo    20

3     2  Mo    14

4     3  Mo    27

5     4  Mo    26

 

To read: On Monday between 0 and 1 o'clock 23 things happened. 

 

The code of the xyplot looks like that:

 

trellis.device(new = FALSE, col = FALSE)

xyplot(Freq ~ Hour | Day, data = mydata,

       xlab = "hour", ylab = "number", main =
"xxx", ylim = 1:30,

       scales = list(x = list(at = seq(0,24,6), labels = c(0, 6, 12, 18, 24),
cex = 0.7, relation = "free"),

       y = list(tick.number = 5, cex = 0.7)), between = list(x = 0.5, y = 1.5), 

       layout = c(4,2), aspect = 1,

       panel = function(x,y){

         panel.grid()

          panel.barchart(x, y, horiz = F, aspect = 1, col = "red")

       }

       )

 

Now my problem:

The plot is ordered by default, that in the first row I can see Friday, Saturday
and Sunday, in the second row there is Monday, Tuesday, Wednesday and Thursday.
I like to order the panels that way that in the first row there should be
Monday-Thursday, the last row to contain Friday - Sunday.

Is there any parameter in xyplot I can add to achieve this result? Any parameter
where I can tell how the panels have to be arranged?

 

Thanks a lot for any help. 

 

Antje

'as.table'.
