Plotting with stplot, mode="xy"

Many thanks Edzer - it is superb to have your help on such occasions.

Checking CRAN - the latest version of spacetime appears to be 0.7-0 - does that mean I need to wait for 0.7-1 (which you refer to) to be released?

I did not copy to the list because I was not sure this question was relevant to my problem.

Best wishes, Barry

Hi Barry, the following should have worked:

library(spacetime)
loadMeuse()
d = as.data.frame(meuse)[c("cadmium", "copper", "lead", "zinc")]
x = STFDF(meuse, Sys.time()+1:4, stack(d))
stplot(x, animate=1, col.regions=bpy.colors(),
   cuts=c(1,10,100,1000,10000))

but doesn't fix the legend with current spacetime on CRAN, as the 'cuts'
argument was not passed on to spplot.

spacetime 0.7-1 in subversion has this fixed.

the 'col' argument needs to be called 'col.regions'.

Hello
 
I am trying to plot some space-time data which encompasses 3654 time
intervals (15 mins each) at 84 sites.
 
I would like to animate these data and so I have used the following code
and my STFDF object is "sp_time":
 
colors.ten<-rainbow(10,start=0.0,end=0.66) # rainbow color scale
stplot(sp_time, mode="xy", animate=1, cuts=10, at=seq(5,55,5),
auto.key=T,col=colors.ten)
 
The first plot I see is this where the points are plotted in the correct
locations:
 
But, I wanted some bespoke rainbow colors which do not appear and I know
the z-range of the data is wider than that shown - the range is actually
between 6 and 44. When I run the animation the scale changes each time
but I would like it to be fixed so that each time slice has the same
scale. Any advice on how I can solve this? I have tried reading the help
pages on levelplot but to no avail.
 
Thanks, Barry
