[R] data point labeling in xyplot

[Duncan Mackay]

Hi 

have a look at the latticeExtra package

library(latticeExtra)
? useOuterStrips

or
xyplot(y~x| paste(grouping1, grouping2), data=na.omit(mydata), layout =
c(...

Subject: [R] data point labeling in xyplot

Hi Folks,

I have data with a format like:

ID    y    param1    param2    groupingFactor1    groupingFactor2.....
1    ...   
1
1
1
2
2
2
2
3
3
3

so several grouping factors and repeated measures. I am using trellis and
xyplot to get plot with several grouping factors.
something like xyplot(y~x|grouping1*grouping2, data=na.omit(mydata),
panel=function{panel.xyplot(x,y);....}); Lets say x is the x axis parameter
and y the one for y.
So this will produce a plot with 4 windows which groups data according to
all combinations of groupingFactor1 and groupingFactor2.

Now I want to label the data points in each of these four plot windows with
the "ID" (ID is an integer representing the subject number). I used the
ltext(x=x,y=y,...), but then it uses the superscripts for the all data set
and dose not mark the data correctly. It only works if I ignore the grouping
and have all my data in one single plot window. It seems that I should
somehow pass the correct subscripts for the data in each plot window (or
group), but I could not figure it out.

thanks,
