Usage
animation(xyt, s.region, t.region, runtime=1, incident="red", prevalent="pink3", pch=19, cex=0.5, plot.s.region=TRUE, scales=TRUE, border.frac=0.05, add=FALSE)
Arguments
xyt
data-matrix containing the (x,y,t)-coordinates.
s.region
two-column matrix specifying polygonal region containing
all data-locations xyt[,1:2].
If missing, s.region is the bounding box of xyt[,1:2].
t.region
interval containing all data-times xyt[,3].
If missing, t.region is defined by the range of xyt[,3].
runtime
approximate running time of animation, in seconds,
but it is longer than expected. Can also be NULL.
incident
colour in which incident point xyt[i,1:2] is
plotted at time xyt[i,3].
prevalent
colour to which prevalent point xyt[i,1:2] fades
at time xyt[i+1,3].
pch
plotting symbol used for each point.
cex
magnification of plotting symbol relative to standard size.
plot.s.region
if TRUE, plot s.region as polygon.
scales
if TRUE, plot X and Y axes with scales.
border.frac
extent of border of plotting region surounding
s.region, as fraction of ranges of X and Y.
add
if TRUE, add the animation to an existing plot.
