Thank you, Erin xYplot does not accept multiple Cbind terms. You'll have to string out your data tall and thin to construct a single Cbind(Y, SE) and use superposition with groups=. Sometimes confidence intervals are better than using +-SE, which also has the advantage of allowing the intervals to be asymmetric.

[R] Hmisc xYplot: two ablines?
Dear r-helpers, Happy New Year. To a plot xYplot(lo ~ vaR, groups = v, data = abc1.fp,aspect = xy, xlab=expression(frac(abs( bold(v) ),abs( bold(a) ))), ylab = grid::textGrob(expression(paste(log, frac( italic(p) ( italic (v) ), italic(p) ( italic(a) ), abline =list(a = 5.71442, b = -5.71442, col = 2) ) I would like to add another abline such as abline = list(a = 8.8460, b = -8.8460, col = 3). Any advice? _ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400Charlottesville, VA 22904-4400 Parcels:Room 102Gilmer Hall McCormick RoadCharlottesville, VA 22903 Office:B011+1-434-982-4729 Lab:B019+1-434-982-4751 Fax:+1-434-982-4766 WWW:http://www.people.virginia.edu/~mk9y/ __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
Re: [R] Hmisc xYplot: two ablines?
To r-help:
Thanks to Mat Soukup for the help:
To draw two ablines:
xYplot(lo ~ vaR, groups = v, data = abc.fp, aspect = xy, col = c
(red,blue),
xlab=expression(frac(abs( bold(v) ),abs( bold(a) ))),
ylab = grid::textGrob(expression(paste(log, frac( italic(p) ( italic
(v) ), italic(p) ( italic(a) ),
panel=function(x,y,...){
panel.xYplot(x, y, ...)
panel.abline(a = 7.985090, b= -7.985090, col = red)
panel.abline(a = 7.926507, b = -7.926507, col = blue, lty = 2)
}
)
This is (to me) a surprising syntactic leap from one abline in
xYplot, which can be requested without writing a panel function:
xYplot(lo ~ vaR, groups = v, data = abc.fp, aspect = xy, col = c
(red,blue),
xlab=expression(frac(abs( bold(v) ),abs( bold(a) ))),
ylab = grid::textGrob(expression(paste(log, frac( italic(p) ( italic
(v) ), italic(p) ( italic(a) ),
panel.abline(a = 7.985090, b= -7.985090, col = red)
)
