parallel rotated strips with color gradient
Hi,
I want to produce two parallel rotated strips with color gradient. So
far, the sample strip is something produced by this:
pushViewport(viewport(x = unit(0.638, "npc"), y =unit(0.386, "npc"),
width=.62, height=0.006, angle=137.2))
grid.rect(y=100:1/100, just="top",

fill=colorRampPalette(c("lightgray",

Defining a viewport scale in {Grid}
Am just feeling my way into the grid library, and cannot figure out how to
define the plot limits. 3/5 of the example polygons below plot in the
default 0-1 range viewport. But when I try to redefine the viewport the
polygons plot in the same places. I also get the same result without
employing push/pop. (As you can see from the scale I'm trying to introduce,
I want to plot map polygons.)

Making use of names of viewports (grid)
The following code, though not brilliant, works on an A4 page. It
might look odd on other devices of a very different size.

vps <- grid.layout(nrow = 3, ncol = 4,
widths = unit(rep(1, 4), rep("null", 4)),

Problem when combining dotplot() and textplot() using grid
Hi everyone.
I want to solve the following problem. I have a data.frame and I
create a dotplot using lattice.
Then I want to use the grid-package to create a combined graphic which
contains the dotplot as well as a textplot() (using package gplots) of
the data.frame next to the dotplot.
Example code:
library(lattice)
library(grid)
library(gplots)
xx <- data.frame(f=factor(rep(1:5, each=5)),

grid.edit problem
I am having a problem in editing a grob. It works ok if I try to
shift the grob using npc coordinates but if I do the same thing
using native coordinates the grob disappears. What is wrong?
library(grid)
grid.newpage()
# create viewport
pushViewport(viewport(xscale = c(100,200), name = "X"))
# draw vertical line
grid.lines(150, 0:1, default.units = "native", name =

Forestplot () box size question
Hi All,
I have been able to modify the x-axis to start at zero by adding xlow
and xhigh parameters; that was pretty simple. I have been unable to
find the location of the code that would turn off the information
weighting of the box size (I have smaller randomized trials getting
less weight than a much larger non-randomized trial). The function
is forestplot() from rmeta.
Thanks for any

Problem with viewports, print.trellis and more/newpage
Dear R-users,
I have got the following problem. I need to create 4x2 arrays of
xyplot's on several pages. The plots are created within a loop and
plotted using the print function. It seems that I cannot find the proper
grid syntax with my viewports, and the more/newpage arguments.
The following script is a simplification but hopefully will suffice to
illustrate my problem. Any suggestion

text length in grid
Hello! I first would like to compliment the authors of grid on what has been
a wonderfully useful package for me. Now, my question: Is there any way I
can specify the size of some grid.text using grid units?
I must label the regions of a plot. The regions can be either very small or
very large, so I would like to label each by fitting its text to the size of
the region in question. Ideally, I

grid layout scaling viewport width based solely on height
Hello all,
I'm trying to write a function that produces a main plotting region
with several square plots along the right side. Ideally the size of
right side plots will scale only with the height of the entire plot,
yet never overlap with another secondary plot. The following two
snippets get close, however, as I resize the plot horizontally the
right side plots (green squares) get smaller

Gridbase basic question
All,
I have a simple plot(x,y) and I would like to then insert rectangles of
some length (in native coordinates) and height fixed to 0.5 in native
coordinates. I can't quite get the code right to do this. Can anyone
give me a quick example of how to do this? I looked the gridBase index
and the tutorial (from R-news?) but just haven't gotten it down yet.

npc to native coordinates for xyplot
Hello,
I am having trouble adding symbols to grid graphics. I am able to
create a lattice scatterplot using xyplot, which has a range from
-15:15 in both the X and Y directions. However, when I try to add
circles and text to this graph using grid.circle() and grid.text(),
they are offset using the default npc coordinates.
Nothing happens when I pass the parameter default.units="native"

Problem going back to a viewport with gridBase
I am setting up base plots -- one in viewport A and and one in B. This part
works fine. But if I go back to A after having done B and add
horizontal lines it seems
to not use the correct coordinates. How do I tell it to resume using A's
coordinates? I am already using par(fig = gridFIG()) but it seems that that's
not enough to reestablish them. What happens is that when I go back to

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.

gridBase and new.page() / grid.newpage()
Hello all,
I'm trying to write a function using the gridBase package. I'd like
to push several base subplots to a larger plot constructed with grid.
However, I'm having trouble getting consistent results when running
the function when the plotting window (quartz) is closed, when it is
left open and the plot function is repeated to the same window, and
when the output is saved to a

Help combining cell labelling and multiple mosaic plots
Dear colleagues
I'm using data that looks like .test and .test1 below to draw two mosaic plots with cell labelling (the row percentages from the tables).
When I take out the pop=FALSE commands in the mosaic commands and comment out the two lines labelling the cells, then the plots are laid out exactly as I'd like: side-by-side.
But I do require the cell labelling and the pop=FALSE

gridBase and heatmap
I would like to use gridBase to place four separate heatmaps (actually,
a stripped-down heatmap.2 from ght gregmisc package that contains only
the "image" part) into four different viewports. I can get the
placement correct, but I keep 'losing' the previous plot. Any
suggestions?
Here is some quick example code trying to put a heatmap into the left

Viewport and grid.draw

I need to add a common legend to a group of latice
