off topic: C/C++ codes for pseudo inverse
Hi,
I am looking for C/C++ codes for computing generalized
inverse of a matrix. Can anyone help me in this
regard?
Thanks,

Grid: constructing a gTree with grobs that use named viewports from a vpTree
I'm trying to create a layout with named viewports that I can use for
other functions. I create the viewport tree that I want, and a list
of grobs with the viewports describing where they should go.
library(grid)
vp <- vpTree(
viewport(layout=grid.layout(2,2), name="layout"),
children=vpList(
viewport(layout.pos.col = 1, layout.pos.row=1, name="tl"),

matrix operations on grobs and grid units
Dear list,
As a minimal test of a more complex grid layout, I'm trying to find a
clean and efficient way to arrange text grobs in a rectangular layout.
The labels may be expressions, or text with a fontsize different of
the default, which means that the cell sizes should probably be
calculated using grobWidth() and grobHeight() as opposed to simpler
stringWidth() and stringHeight().

grid - deleting and erasing grobs?
Hello!
Don't quite understand how can I delete grobs and simultaneously erase
graphic output they produce. I first change grob's "vp" field to null
(grid.edit(gr,vp=NULL)) to erase it and then call rm(gr) (as grobs are
external pointers I'm not shure what this method actually frees
allocated memory).
May be there is simpler method?
Does garbage collector have any effect

Examples of multiple key grobs
The xyplot help page gives quite a lot of information how to use key
and indicates that legend needs to be used if multiple keys are
needed. However, it gives only a brief description of what the grob
needs to contain to do multiple keys.
I've only used the occasional grid function in panel functions, so I
don't have much of a sense of how grobs are constructed. I've been
unable to

ggplot2 - getting at the grobs
Dear All,
I continue trying to get several of my plotting functions to use
ggplot, because I really do like the concept of the graphical
objects, and working with them in the abstract.
I am now trying to access the grobs to manipulate using grid.
However, until now all I managed was to get the plot as a gTree
object, and manipulate it as a gTree from there. The problem is that
then it is no

ggplot2: Changes to grobs not saved to file output
Hello,
Maybe I missed something - most likely .:-(
I create a gplot and then makes some changes to the plot using grid graphics
functions. These changes show up on the display OK, but when I save using
ggsave() the grid changes do not show up. How do I save the plot with these
changes?
Thanks in advance.

Location of grobs etc on lattice output
Is there any way, after use of print.trellis(), to obtain the
co-ordinates of the plot region, e.g., in what are then the
native co-ordinates?

library(lattice); library(grid)
data(cuckoos)
pushViewport(viewport(layout=grid.layout(2, 1)))
pushViewport(viewport(layout.pos.row=1))
cuckoos.strip <- stripplot(species ~ length, data=cuckoos)
print(cuckoos.strip,

package grid: mirror grob objects along an axis
Hi everyone
I'd like to flip grobs (grid graphical objects) along an axis, e.g. flip grobs
horizontally or vertically. I couldn't find any hints, neither in the
documentation nor by searching the web. Does anybody know how to achieve this?
Cheers

Small issue with R's C API
Consider the R code:
mat <- matrix(seq(1,20),4,5)
is.matrix(mat) # gives TRUE
is.vector(mat) # gives FALSE
On the other hand, if mat is passed through the .Call interface the
corresponding SEXP (call it smat) satisfies
isMatrix(smat) // TRUE
isVector(smat) // TRUE
Consequently, you cannot distinguish matrices from vectors. Looking
at the dim attribute of a vector doesn't help because

childNames for xaxis grob (grid package)
Dear list,
Can someone explain why the childNames below
gives

instead of the (canonical) names of the children grobs
of the xaxis gTree ?

Many thanks in advance,

rbind problem (PR#338)
In the new version 0.90.0, rbind won't take a vector and a matrix from me,
but works OK if I coerce the vector to a matrix. The following was run on
a new session (i.e., no prior work), and has been duplicated on 2
machines: an SGI running Irix 6.5, and an Intel box running Red Hat Linux
6.0.
Either case works fine in version 0.65.1.

lattice grob
Dear list,
I'm trying to arrange various grid objects on a page using a
frameGrob. It works fine with basic grobs (textGrob, gTree, etc.), and
also with ggplot2 objects using the ggplotGrob() function. I am
however stuck with lattice. As far as I understand, lattice produces a
list of class trellis, which is eventually displayed using the
plot.trellis method. I am not sure if/how one can

I've been studying some of the code and I'm still a little shakey on the

GenGC changes
As most R developers maybe are already aware of, R version 1.2.0
introduced a new `generational' garbage collector which means that
strings and vectors (and language objects) are handled differently from
the numerical atomic types.
>From ``Writing R Extensions'':
Earlier code was written in a style like.
