Re: [R] xYplot customizing y-axis scaling
Hi Henning, have a look at the scales argument in the xyplot documentation. You could try adding the following to your code: scales=list(y=list(relation=free)) Cheers, Christoph Thursday, July 10, 2008, 4:35:28 PM, you wrote: Dear list, using the packages Hmisc and lattice i produced some nice xYplots. However, since the data range of the conditioning variable is very big, i need to define more than one y-scale for the plot (in some panels you just see a flat line of data points very close to the x-axis), e.g. different y-axis scales for the different rows of the plot.

Re: [R] Separate y-limits in xYplot panels II
Hi John, I think even with scales=list(y=list(relation=free) you have to specify the y-limits for each panel, i.e. add something like ylim=list(c(0,1200),c(0,1)) to your code.

Re: [R] Overlay plots from different data sets using the Lattice package
Hi all,
I'm a newbie to lattice graphics. I think I have a very similar problem
trying to overlay plots from different data sets. I tried a number of
different things but don't seem to get it to work. I am using xYplot from
library Hmisc to produce a lattice plot with Median plus error bands plotted
as lines for each panel. This works fine. Now I want to add specific points
to each panel, however, the data for those points are in a different data
frame. I tried something along the lines of Deepayan's example, combining
the two data sets using make.groups, but that doesn't seem to work. My code:
data=read.table(all species.txt,header=T)
data.nonrandom=read.table(all species_non-random.txt,header=T)
combined=make.groups(data,data.nonrandom)
xYplot(Cbind(Median,Lower,Upper)~species.pool|data.set.location,
data=combined,subset=response.variable==sr,groups=which,method=bands,col=black,type=l,
panel.groups=function(x,y,group.number,...) {
if(group.number==1)
panel.lines(x,y,...)
else panel.points(x,y,...)
})
This gives me the 3 lines per panel that I want (Median plus error bands)
but what I want to add as points is instead also shown as a line with the
group labels (data and data.nonrandom) next to it. Any ideas what I am
doing wrong? Any help and suggestions would be much appreciated! Many thanks
in advance.
Best regards,
Christoph

The first step would be to combine the two data sources:
df.comb - make.groups(data.frame.A, data.frame.B)
I would then just overlay two density plots:
densityplot(~vals | factor.1 * factor.2, df.comb,
groups = which, plot.points=FALSE,
auto.key = TRUE)
but you could do a histogram and a densityplot too:
histogram(~vals | factor.1 * factor.2, df.comb,
type = density,
groups = which,
panel = panel.superpose,
panel.groups = function(x, group.number, col, ...) {
if (group.number == 1)
panel.histogram(x, ...)
else
panel.densityplot(x, ..., plot.points = FALSE)
})
