Hello All.
I would like to repeat a multi-screen, multivariate time series plot across
multiple units.
Consider the following data:
<
[hidden email]> UNIT TRIAL Y1 Y2 Y3 Y4
Y5 Y6
1 109 1 NA NA NA 13718 3655 15240
2 109 2 15000 6000 30000 13057 6198 21962
3 109 3 10000 10000 20000 8356 12929 27992
4 109 4 10000 10000 20000 12642 10978 34843
5 109 5 20000 20000 40000 10335 25754 64060
6 109 6 20000 20000 40000 4591 23706 30256
7 109 7 20000 20000 40000 5743 29107 43887
8 109 8 2000 20000 22000 7800 17717 35294
I want to structure this graph to present 3 screens that each represent 2
time series over TRIAL. The following code gives me just what I'm looking
for.
library(zoo)
library(lattice)
z <- zoo(data.matrix(ii_df[,3:8]), ii_df[,2])
xyplot(z, screens = c(1, 2, 3, 1, 2, 3), col = 1:6, pch = 1:6, type = "b")
This works great. Now, I'd like to repeat this basic graph for 100 levels
of UNIT. I have two questions.
First, I've tried to replicate this method using a trellis graph without
much success. Is there a way to replicate this plot across UNITS using a
trellis graph?
Second, the trellis graphs I have been able to make result in plots that are
too small to read. How could I loop this graphing routine to yield the
graph I get above in my zoo code for each of the 100 distinct units?
Thanks in advance,
Rick
