I am trying to graph weight data for our colony. We a data frame with
Animal, Weight and Date. I'd like to display this data a series of simple
xyplots. We only need to display these plots together, we do not need to
make comparisons between animals. Each animal has been weighted over a
different time period, so we do not want the same range for each X axis.
Using the following, I can create one plot per animal:
size - length(unique(data$id))
xyplot(weight ~ date | id,
data=data,
#type=o,
layout=c(1,size),
xlab=Date,
ylab=Weight
);
However, they share a common X axis. Is it possible to avoid this? In
other words, I might want the first animal's plot to extend from
2008-01-01
through 2009-05-04, while the second plot extends from 2007-02-04 through
2010-01-01.
Also, can I introduce more whitespace between each plot?
Thank you for any help.
You can do this in ggplot2 using facet_wrap( ~ id, scales = free_x ):
colonyPlot - qplot( date, weight, data = data,
xlab = Date,
ylab = Weight ) +
facet_wrap( ~ id, scales = free_x ) +
theme_bw()
print( colonyPlot )
Not sure about hot to do it using xyplot though. The following website may
help for ggplot2:

Good luck!
