Hi,
How does one change the dot for the median in a boxplot drawn using
lattice? I have been looking at
> names(trellis.par.get())
[1] "grid.pars" "fontsize" "background"
[4] "panel.background" "clip" "add.line"
[7] "add.text" "plot.polygon" "box.dot"
[10] "box.rectangle" "box.umbrella" "dot.line"
[13] "dot.symbol" "plot.line" "plot.symbol"
[16] "reference.line" "strip.background" "strip.shingle"
[19] "strip.border" "superpose.line" "superpose.symbol"
[22] "superpose.polygon" "regions" "shade.colors"
[25] "axis.line" "axis.text" "axis.components"
[28] "layout.heights" "layout.widths" "box.3d"
[31] "par.xlab.text" "par.ylab.text" "par.zlab.text"
[34] "par.main.text" "par.sub.text"
I tried playing around with dot.line and dot.symbol but could not
figure out what to do. Is there anything else I could try.
As a reproducible example, we can consider:
library(lattice)
bwplot(voice.part ~ height, data=singer, xlab="Height (inches)")
I want the dots for the medians to be replaced by a line through the
median.
Any suggestions?
Many thanks,
Ranjan
PS; Also, how do I get the rectangles to be filled? I tried the
following:
box.rectangle <- trellis.par.get("box.rectangle")
box.rectangle$fill<-"opaque"
(also tried "filled", "shaded", etc. to no avail)
trellis.par.set("box.rectangle", box.rectangle)
but get errors in plotting.
Many thanks again and best wishes,
Ranjan
