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.
