Dear R users,
I am trying to use xyplot to draw group mean and CI. The following is the
sample code.
[attached code snipped]
Did you try the plotmeans function from the gplots package?
But I want:
1. Use different colors and symbols to draw individual points, CI and
the lines connect group means from different time points;
2. Add jitters to x axis to allow CIs not be overlapped
Both of these two requirements are covered in the options of the
plotmeans function.
