panel.segplot {latticeExtra} | R Documentation |
Draws line segments or rectangles. Mainly intended to be used in
conjunction with the segplot
function.
prepanel.segplot(x, y, z, subscripts, horizontal = TRUE, ...) panel.segplot(x, y, z, level = NULL, subscripts, at, draw.bands = is.factor(z), col, lty, lwd, border, col.regions = regions$col, band.height = 0.6, horizontal = TRUE, ..., centers = NULL, pch = 16)
x, y, z |
Vectors corresponding to x1 , x2 and
y respectively in the segplot formula. The names are
different for compatibility with panel.levelplot . These are
all the original vectors in data , not subsetted for
particular panels. |
level |
optional vector controlling color of segments |
centers |
optional vector of ‘centers’ of the segments.
If specified, points will be plotted at these y -locations. |
pch |
plotting character used for centers . |
subscripts |
integer subscript to be used as an indexing vector
for x , y , z and level , giving the packet
for the current panel. |
horizontal |
logical, whether the segments are to be drawn horizontally (the default) or vertically. This essentially swaps the role of the x- and y-axes in each panel. |
at |
values of level where color code changes |
draw.bands |
logical, whether to draw rectangles instead of lines |
col, lty, lwd, border |
graphical parameters. Defaults to
parameter settings for "plot.line" or "bar.fill" for
segments and rectangles respectively. col is overridden by
col.regions if level is not null. |
col.regions |
vector of colors as in levelplot |
band.height |
height of rectangles (applicable if
draw.bands is TRUE |
... |
other arguments, passed to panel.rect or
panel.segments as appropriate. |
