Plot Area Dimensions
Dear colleagues,
I wish to create a figure with 6 plots arranged vertically with no spacing
between them as they all have a common x-axis.
However, using the code below I'm unable to get the plot area the same size
for each plot.
The bottom plot with the x-axis label is smaller than the others, as is the
top plot which has larger margins.
How can I get the plot region the same size for

Graph Order in xyplot
I have constructed a Trellis style xyplot.
lengthf <- factor(length)
xyplot(SLI$velocity ~ SLI$width | SLI$lengthf, layout = c(2,7), xlab =
"Width (cm)", ylab = "Velocity (m/s^2)", col = "black")
This produces a lovely little plot. However, the grouping factor(lengthf)
isn't in the right order. My values range from 2-28 and the 2 graph on the
bottom left and

Poisson Maximum Likelihood Estimation
Hi
I am trying to carry out some maximum likelihood estimation and I'm not
making much headway, and I'm hoping that someone will be able to point me in
the right direction.
I am modelling mortality statistics. One way to do this is to model the
mortality rate (or, more accurately, log of the mortality rate, log_m) as
(say) a constant plus a proportion of age, plus time, so:

Apparent different in symbol scaling between xyplot and grid.points
Dear R-users,
For the past few days, I have been trying to find the reason why some of
my plots were showing symbols of different sizes, while I thought I was
using the same .cex arguments everywhere. The problem is exemplified by
the following example code where the xyplot and grid.points functions
are used. The scaling factor is set to 0.84 in both the functions
settings, but one can see

highlighting subset of point with xyplot (or Hmisc(xYplot))
Hello all,
I am trying to use xyplot to give a six panel plot and to highlight
only points (in any panel) that meet a certain criterion. With the
plot command I would do something like:
plot.default(filein$Site,filein$circ.conc)
points(filein$Site,filein$circ.conc,type="p",
pch=ifelse(filein$p.value<5e-02,19,21))
I had thought I could just stick in the pch line from above into

lattice::xyplot() with one factor for points and another for lines
Hi:
In lattice, how does one handle separate graphical behavior for two
different factors? In the xyplot below, the objective is to use the levels
of one factor to distinguish corresponding shapes and colors, and the levels
of the other factor to perform level-wise loess smooths.

d <- data.frame(time = rep(1:8, each = 6), val = rnorm(48),

point characters THICKER in xyplot()
Hi, how can I make the point characters thicker (NOT larger) in xyplot when
groups= argument is used?
dat<-data.frame(x=1:100,y=1:100,group=rep(LETTERS[1:5],each=20))
### lwd=2 doesn't work here
xyplot(y~x,groups=group,data=dat,col=1:4,pch=1:4,lwd=2)
### lwd=2 works with panel.points(), but grouping is messed up!

Can I add a point to a pointsGrob from an xyplot without redrawing ?
Hi:
I am a newbie using grid and lattice.
I want to update a xyplot without redrawing and I was wondering if there is
a way of adding a point to a pointsGrob ?
For example, take the example from the "R Graphics Book" page 218-219:
grid.newpage()
angle <- seq(0, 2*pi, length=21)[-21]
x <- cos(angle)
y <- sin(angle)
xyplot( y ~ x, aspect = 1)

Mixed font in lattice xyplot lables

Spacing and margins in lattice...
Similar to my last question, I want to tighten up the spacing and

Hmisc xYplot
Dear R community,
I am having trouble with a particular plot that I am trying to produce
using Hmisc's xYplot function. I've been using primarily lattice and
Hmisc packages for my plotting needs for the past few years, with great
success.
However, what I want to do now with xYplot is plot more than one data
trend in the same panel, much as I would use xyplot from package

plotting curve in xYplot -- using panel.curve
Hello,
I am trying to plot a curve over points plotted with se's in xYplot (see
example below). I can get Figure 1 below to plot the data with error.
However, I keep getting a the error message
"Error using packet 1 object "y" not found"
Can anyone see what I am doing wrong?
Thanks!

lattice xyplot: plot multiple lines with different colors
Hi everyone,
I am using the lattice package to plot some simulation results, by using
the function xyplot(). However, I cannot find a way to plot multiple
lines within the same xyplot and to have each of the lines be drawn in a
different color.
This is what I am currently doing:
xyplot(a + b + c ~ x, my_data, panel = panel.lines)
but, of course, all lines are drawn in the same color.

Specifying point symbol fill colour in lattice xyplot keys
Dear all,
When defining explicit keys with xyplot, I have previously used the fill
parameter to set the background colour of point symbols. That's no
longer working for me, and I am wondering whether it's a bug or whether
I've misinterpreted the documentation and have been relying on a feature
wasn't intended. If the latter, can anyone suggest the correct way to do it?

lattice/xyplot: plotting 4 variables in two panels - can this be done?
Hi,
I would like to create a plot of y1,y2,y3,y4 against x for several subjects such that y1 and y2 are plotted against x in one panel and y3 and y4 against x in another panel. Thus if there are 3 subjects I should end up with 6 panels. Is there a simple way of doing so (i.e. without calling xyplot() several times, and then padding the results together)??

second y-axis in lattice xyplot
Dear R-help,
I recently discovered lattice xyplot, but have been struggling with plotting a second y-axis. I am able to do this with plot() but can't figure it out in xyplot. Any help would be appreciated.
I have found help on adding a second Y-axis when the data is all part of the same data frame, but I have two different data frames.
Both data sets are being plotted against "Date".

problem with xyplot
Hi all,
I am having a problem using xyplot from lattice library. I am plotting one
variable against another one, conditioning on two other variablesm one of
which has 3 levels and the other 6 levels. The output is thus a 6x3 panel
plot. Here's my code:
