Hi everyone,
I'm very new to R and I like to learn a lot... actually I have a little
problem concerning errorbars with xyplot.
My data look like
run target hemi x
1 1 Nichts Links 0.0007743240
2 2 Nichts Links -0.0008153365
3 1 Target Links -0.0015825950
4 2 Target Links 0.0088743785
5 1 Nichts Rechts 0.0015898995
6 2 Nichts Rechts -0.0011465190
7 1 Target Rechts -0.0022225320
8 2 Target Rechts 0.0039010500
these data I plotted with xyplot(data=dummyy,
x~hemi|target,groups=run,type="p")
the same I do have with standard errors of means...
How could I attach errorbars to the datapoints? I found some R-code from
Dec 2002 but I dont work (and I did not understand it...)
Thanks for helping me, maybe others out there will find it usefull too.
Best
Ronny
