Dear R-helpers,
(1) I can't figure out how to tell Dotplot that I want the colors of
the CI bars to be the same as the colors of the dots.
For example:
t2a.ci3 <- data.frame(est = c(7, 20, 75), lower = c(-9, 0.5, 42),
upper = c(22, 39, 109))
mypal <- c('skyblue3', 'mistyrose3')
condNames <- c('noise', 'horn', 'marimba')
Dotplot(1:2 ~ Cbind(est, lower, upper), data = t2a.ci3,
scales = list(y = list(at = 1:2, labels = condNames)),
ylab = '',
xlab = 'rated duration', aspect = 0.2,
ylim = c(0.5, 2.5), panel = function(x, y){
panel.Dotplot(
x, y, col = mypal[c(1, 2)],
col.segments = mypal[c(1, 2)])
panel.abline(v = 50, col.line = 'red', lty = 2)}
)
My guess was "col.segments" but that doesn't do the trick.
(2) How do I insure that as I change the number of lines and ylim I
just change the the height of the y-axis, keep the distance between
horizontal lines constant, and do not add white space above and below
the figure? This shows how white space changes:
Dotplot(1:3 ~ Cbind(est, lower, upper), data = t2a.ci3,
scales = list(y = list(at = 1:3, labels = condNames)),
ylab = '',
xlab = 'rated duration', aspect = 0.3,
ylim = c(0.5, 3.5), panel = function(x, y){
panel.Dotplot(
x, y, col = mypal[c(1, 2, 1)],
col.segments = mypal[c(1, 2, 1)])
panel.abline(v = 50, col.line = 'red', lty = 2)}
)
