stplot: produce trellis plot for STxDF object

Description

create trellis plot for ST objects

Usage

stplot(obj, ...)
stplot.STFDF(obj, names.attr = index(obj@time), ..., as.table = TRUE)
stplot.STIDF(obj, names.attr = NULL, ..., as.table = TRUE, by =
    c("time", "burst", "id"), scales = list(draw = FALSE), xlab =
    NULL, ylab = NULL, type = 'p', number = 6, overlap = 0, asp)

Arguments

obj

object of a class deriving from ST

names.attr

names that will be used in the strip

as.table

logical; if TRUE, time will increas from top to bottom; if FALSE, time will increase from bottom to top

by

conditioning variable(s); in case time is conditioning variable, it will be classified using equal.count, using parameters overlap and number

scales

scales drawing; see scales argument of xyplot

xlab

x-axis label

ylab

y-axis label

type

character; use 'l' for lines, 'p' for symbols, 'b' for both lines and symbols

number

see argument by

overlap

see argument by

asp

aspect ratio of plot

...

arguments passed on to spplot in case of stplot.STFDF, or to xyplot in case of stplot.STIDF

Value

• stplot is a wrapper around spplot, that automically plots each time stamp in a panel.
