animated grid graphics
I need to make a fairly complex animated graphic and decided to use grid for it.
A very simple example of what I need:
##==============================================================================
library(grid)
grid.newpage()
pushViewport(plotViewport())
pushViewport(viewport(xscale = extendrange(c(0, 100)),
yscale = extendrange(c(0, 100))))
grid.xaxis()
grid.yaxis()

Window on a vector
Dear all,
I have a large vector (lets call it myVector) and I want to plot its value with the logic below
yaxis<-myVector[1]
yaxis<-c(xaxis,mean(myvector[2:3])
yaxis<-c(xaxis,mean(myvector[4:8])
yaxis<c(xaxis,mean(myvector[9:16])
yaxis<c(xaxis,mean(myvector[17:32])
this has to stop when the new ..... yaxis<c(xaxis,mean(myvector[1024:2048]) will not find the correspondent number

childNames for xaxis grob (grid package)
Dear list,
Can someone explain why the childNames below
gives
character(0)
instead of the (canonical) names of the children grobs
of the xaxis gTree ?

Many thanks in advance,

boxplot and xlim confusion?
I have some code as shown below. Basically, I would like three
boxplots to be set next to each other with no ylabels on the two
"inner" plots, and I want the same x axis range on all three. However,
it seems like boxplot does not respect the xlim setting. I've tried
the various ways I thought would work (par, boxplot(...xlim=)) but
none of them seem to work. I then tried plot.window,

Not to draw the xaxis ticks in ggplot2
>library(ggplot2)
>(p<- qplot(mpg, wt, data=mtcars))
What I am doing is to set color of the ticks to hide them.
>grid.gedit(gPath("xaxis", "ticks"), gp=gpar(col="white"))
It should be a better way to achieve the purpose. Thanks.

abline(v= x) in plot with time formated xaxis not working
Hi,
I try to create a vertical line in my plot, which has a xaxis comprising
time formated data.
This is what I tried:
----------------
y<-152833
x<-strptime(y, format="%H%M%S")
abline(v=x, col="red")
----------------
for some reason, it doesn't work and no error msg is displayed...
I hope someone can tell me what I do wrong, or maybe an alternative.
Thanks

barplot and ylim - display problems
The following single line of code shows what I am trying to do, and the
problem I am having...
barplot(c(101,102,103),ylim=c(100,103))
The 'xaxis' is missing, and the grey bars 'fall off' the plot area. This
is generally ugly, and I would like to trim the bars (ideally they would
have a ragged appearance to show that I am 'zooming in').
I can see why what I am trying to

Setting lattice par parameters
Hello
I'm plotting a large suite of barcharts and need to modify the size of the

I've tried using the following:

trellis.par.set(list = par.xlab.text = list(cex = 0.65))))
On inspection, however after I invoke this line,

Would like to add this to example for plotmath. Can you help?
Greetings:
I would like comments on this example and after fixing it up, I need
help from someone who has access to insert this in R's help page for

Trouble combining plotmath, bquote, expressions
I'm using R-2.6.2 on Fedora Linux 9.
I've been experimenting with plotmath.
I wish it were easier to combine expressions in plotmath with values
from the R program itself. There are two parameters in the following
example, the mean "mymean" and standard deviation "mystd". I am able
to use bquote to write elements into the graph title like
mu = mymean
and R will

control of scat1d tick color in plot.Predict?
Hi All,
I have a quick question about using plot.Predict now that the rms package
uses lattice. I'd like to add tick marks along the regression line, which
is given by data=llist(variablename) in the plot call. The ticks show up
fine, but I'd like to alter the color. I know the ticks are produced by
scat1d, but after spending a fair bit of time going through documentation,

plotmath vector problem; full program enclosed
Here's another example of my plotmath whipping boy, the Normal distribution.
A colleague asks for a Normal plotted above a series of axes that
represent various other distributions (T, etc).
I want to use vectors of equations in plotmath to do this, but have
run into trouble. Now I've isolated the problem down to a relatively
small piece of working example code (below). If you would

plotmath "overstrikes" in output on a Linux system
I've been testing plotmath. But I'm getting some funny output one one
computer. The problem is that characters are 'jumbled' and overstrike
when symbols are introduced.
Sample code:
mu <- 440.0
sigma <- 12.5
myx <- seq( mu - 4*sigma, mu+ 4*sigma, length.out=500)
myDensity <- dnorm(myx,mean=mu,sd=sigma)
# Here's one way to retrieve the values of mu and sigma and
