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

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,
library(grid)
rotate.polygon <- function(g, angle=0){ # utility function, works fine
matR <- matrix(c(cos(angle),

Viewport and grid.draw
Hi Deepayan and everyone,
I need to add a common legend to a group of latice
graphs, I have tried different ways using viewport and
grid.draw without success.
Here is what I have:

library(grid)
library('IDPmisc')
print(plot1, split=c(1,1,2,4), more=TRUE)
print(plot4, split=c(2,1,2,4), more=TRUE)

Creating grid graphics with grid.layout
Hi,
I recently created a function which uses grid with a viewport
constructed with grid.layout() to position four plots on a plot device.
My question is what's the best way to programatically traverse each
element of the viewport?
The grid is 5x5 and the four plots occupy positions (2,2), (4,2), (2,4),
and (4,4).
Here's the viewport code:

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

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.ls() after grid.remove() fails
Dr Murrell and others,
It seems grid.ls() fails after any use of grid.remove(). It gives an
infinite recursion error even in the simplest cases, and no matter
what arguments are passed to grid.ls.

> grid.newpage()
> grid.lines(name="foo")
> grid.ls()

offset labeling boxplots
Hello everybody,
often I plot boxplots with different number of boxes (up to 200 boxes).
I'd like to give every box a readable label on the x-axis. Therefore, I
decrease the fontsize of the names and plot them vertical.
But if you zoom into the plot (pdf) you will find an offset between the
tickmark and the label - the label is shifted to the right.
If you vary the box.count in the

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

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

Lattice device page options-margins
I am using lattice to make figures as pdfs:
trellis.device(device = "pdf",file = "Figure6.pdf",color = FALSE)
I need to specify some blank space on the left-hand margins (the pages
will be bound so we need about 0.5 inch)). I have tried a number of
solutions but none seems to work (e.g. par.set). Can this be done when
initiating the plotting device? Or is the some other way

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.)

I'm trying to produce a plot via xyplot with minimal sourounding white

around my plot. However, this is quite a problem for me as I want to
