Bug in viewport handling?
Hi,
Is the following an (unknown) bug? Rhythmbox (RB) has an option for
using a icon-tray. Restoring/minimizing to the tray in combination with
switching viewports (VP) seems to confuse compiz.
Steps to reproduce: 
1. Start RB on VP1. 
2. Minimize to tray.
3. Change to VP2.
4. Click the tray icon to restore.
Result: RB is restored to VP2, while compiz changes to VP1. Subsequent
clicking on the

strange behaviour with rotated viewports in grid
Dear all,
	I am having a problem using grid when rotating a viewport. It seems  
to plot everything on a grey background colour which I am not able to  
get rid of. Even book examples such as that that plot figure 5.10 in  
P. Murrell's R Graphics book show the same behaviour.
	The following example illustrates this issue. I would appreciate if  
anyone has a way to solve this.
	Best regards,

key position in trellis plotting area
Hi, 
 
I want to do the following:
 
1) create a trellis plot with 1 x 1 layout
2) add a key in the upper right hand corner of the plotting region (i.e.,
the panel), but after the initial call to trellis
3) resize the resulting device graphics device without changing the relative
position of the key
 
For instance, the code below draws the key relative to the device
window--not the plotting area.

exact relative positioning of lattice plots
Hello,
I have two lattice plots for which panel.height is fixed.  I am trying to position them in a column so that there is exactly half an inch of vertical space between them.  This would be a simple task if I were not fixing panel.height.  But given that I am, I can't find a way to put exactly half an inch of space between the plots.  Is there a way?  
I've checked the Sarkar and

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:

Problem with grid.rect
I have a stupid problem that is currently driving me crazy...
Let us suppose that I want to draw a big red square in the middle of my
current device (say X11)
I tried the following code :
pushViewport(viewport(xscale=c(0,1), yscale=c(0,1)), just=c("center", "center"))

ask for help on nonlinear fitting
I have a table like the following. I want to fit Cm to Vm like this:
Cm ~ Cl+Q1*b1*38.67*exp(-b1*(Vm-Vp1)*0.03867)/(1+exp(-b1*(Vm-Vp1)*0.03867))^2+Q2*b2*38.67*exp(-b2*(Vm-Vp2)*0.03867)/(1+exp(-b2*(Vm-Vp2)*0.03867))^2
I use nls, with start=list(Q1=2e-3, b1=1, Vp1=-25, Q2=3e-3, b2=1,
Vp2=200). But I always get 'singlular gradient' error like this. But

Legend
I have recently converted from S-Plus (Dec Alpha) to R (Mandrake 10.0). The
differences are subtle but in some cases not easily converted. My Splus
Command plotting deck was over 1200 lines and R has simplified this down to
900 lines so far. I do a lot of mapping with polygons and I am trying to
figure out how to increase the default size of the fill boxes in the legend
call. Splus had a

controlling panel.width and panel.height in viewports
Dear all,
I'm trying to get a series of lattice levelplots to appear in 
viewports in a particular way but struggling to exert fine control 
over their appearence.  There are two conditions: (a) I only want the 
levelplot to appear (I don't want axes, colour key, etc) in the 
viewport and (b) I want the levelplot to expand to the maximum 
allowable space in the viewport while observing

skipping rows in trellis key
Hi, 
 
I would like to add a key to my trellis plot using draw.key. Here is what I
want:
 
3 x 6 key where the first row is a header.
 
row 1: empty, "S-R Mapping", "R^2"
row 2: pch=17, "Color", 0.951
row 2: pch=17, "Shape", 0.934
ect...
 
The problem is that I would like the cell in the upper left corner to be

location of key in panels of trellis plot
Hi,
 
I want to insert a key into each panel of a trellis plot, which I can do
with a custom panel function that calles draw.key. The problem arises
because I want the top right hand corner of the key to start in the top
right hand corner of the panel. If you run my code below, you can see that
the key appears in the center of each panel. This is because the default
viewport in draw.key is the

multiple plots in a function()
Dear all, 
I have the following problem:
I have written a function genereating to plots, eg
myfunction <- (data, some.parameters) {
        #some calculations etc
        .
        par (mfrow=c(1,2))
        plot1(......)
        plot2(.....)
}
which works fine. But for analysing several variants, I tried a slope, eg:
 
par (mfrow=c(5,5))
 for ( i in 1:10) {
    myfunction(data, i)
}

help with double looping
hi there,
I have a dataframe in the shape vA1, vA2,..., vA11, vB1, vB2,..., VB11,......., VP1, VP2,...., VP11 (so 16 times a sequence of 11 variables)
I am trying to build a double loop so that i can apply the function (i-1)*v(i) to the first 10 variables, then the same for the next 10 variables, etc... 16 times.
I have tried the following with no luck:

Dear all,
I'm puzzled by the behavior of stringHeight in the grid package.
Consider the following test,

  g2 <- rectGrob(height=grobHeight(g1), width=grobWidth(g1))
  gg <- gTree(children=gList(g1,g2), ...)

I've rolled up R-1.9.0.tgz a short while ago. This is a new version
with a number of new features, most notably a substantial
reorganization of the standard packages, a major update of the grid
package, and the fact that underscore can now be used as a regular
character in variable names. See below for further changes.

gradient fill of a grid.polygon
Dear list,
Following a recent enquiry, I've been playing with the idea of creating a
colour gradient for a polygon, using the Grid package. The idea is to draw a
number of stripes of different colours, using the grid.clip function. Below
is my current attempt at this,

Width of a plotting point (in inches) in grid package
Hello,
I'm trying to determine the width of a plotting point (in inches) in the
grid package. I naively thought I could create a pointsGrob with only one
point and get the width (as tried below), but this results in an object with
a size of 0inches (changing cex has no effect). Does anyone have a better
approach? Of course, it would be dependent upon the graphics parameters and
viewport...

Why are the rotated blue and yellow boxes in the example below clipped outside of 6 x 6 inch window in the middle of the page?? Where does the 6 x 6 inch window come from? I would like to make use of the entire page.
