Hi,
I have a question about stplot.
Let's say I'd like to plot via multi-panel a series of plots separated by a
given time interval. How can I accomplish that?
Also, let's say this time interval is specified between thow given time
instances, for example: every week between 14/07/11 and 28/08/1
Mathieu,
as stplot for STIDF's is still pretty "bare", or simple, you might as
well work directly with xyplot from lattice. Having your data, it turns
out you only have a limited number of dates, the following seems to work:
library(lattice)
xyplot(y_sref~x_sref|time, as.data.frame(ciotat.t),
Ok,
May I ask you another question?
When I use parameter number for stplot, how does it decide to split plots by
number?
The orange mark on the top of each plot shows me that it isn't by equal time
intervals. I guess it is by equal object count?
Is there a way to indicate time periods on top of
Mathieu,
you may want to look into cut methods for Date, e.g. in your example:
xyplot(y_sref~x_sref|cut(time,4), as.data.frame(ciotat.t))
