Forking and adapting an R package
Hello.
I'm trying to adapt the package ?hexbin? to suit my needs. This is the first
time I do this. I've read a bit through Hadley's ?R packages?, but now I'm
pretty lost (from a workflow point of view). I am using RStudio and Hadley's
devtools.
So I forked the repo I want to adapt: https://github.com/grssnbchr/hexbin and
cloned it using RStudio (I created a new project).

panel.levelplot() for 2D histograms
Dear R-wizards,
I'm trying to plot "binned scatterplots", or 2d histograms, if you wish, for
a number of groups by using the lattice functionality
it works fine for one group at a time, and probably I could find a
work-around, but I prefer to do it the elegant way
here's an example of what I want, what I tried and where it goes wrong:
require(gregmisc)
require(lattice)

multiple hexbin plots with varying greatest densities
Greetings:
I have multiple hexbin plots with varying greatest densities.
Right now, the data on each plot varies from 1-256 levels of density. The problem with that is that in Plot A the data are more scattered across a 2 x 2 grid whereas in Plot B the data are more concentrated in fewer cells. Hence, Plot A has a few very dense grid cells and plot B has nothing as dense as plot A.
(In Plot A

Design for classes with database connection
Dear R-Devels,
I am designing right now a package intended to simplify the handling of market microstructure data (tick data, order data, etc). As these data is most times pretty huge and needs to be reordered quite often (e.g. if several security data is batched together or if only a certain time range should be considered) - the package needs to handle this.
Before I start, I would like to

tensor product of equi-spaced B-splines in the unit square
Dear all,
I need to compute tensor product of B-spline defined over equi-spaced
break-points.
I wrote my own program (it works in a 2-dimensional setting)
library(splines)
# set the break-points
Knots = seq(-1,1,length=10)
# number of splines
M = (length(Knots)-4)^2
# short cut to splineDesign function

gplot.hexbin - how to set figure margin.
Hi,
Would like to use to the hexbin package to plot a 2D hist - because it looks really _cool_.
My problem is related to drawing a pdf hexbin graphic in series of other graphics.
All other figures have a par(mar=c(3.2,3.2,1,1)). So the gplot.hexbin figure in this series looks a little alienated?
Was trying a to specify the _mar_ using par, viewport, hexViewport etc. a little.
My question. How

hexbin and grid - input data values as coordinates
Dear all,
I am trying to use hexbin and read the very interesting article on grid
( http://www.ci.tuwien.ac.at/Conferences/useR-2004/Keynotes/Murrell.pdf ) and am hoping for some advice from more experienced users of hexbin.
I am trying to visualise a data and fit a straight line trough it. For
example, here is how I would do it in the usual way

Using grid graphics (hexbin) in pairs() plot problem
Hi,
I am trying to create a plot with pairs()
using a gplot.hexbin() for each pair.
For pairs I can provide a custom upperPanel function:
pairs(iris[1:4], panel=mypanel)
and mypanel() calls plot.hexbin():
library(hexbin) # Bioconductor
mypanel <- function(x, ...){
hb <- hexbin(x)
plot(hb)
}
The problem is that gplot.hexbin() is based
on the

sunflower plot, making vectors?
I'm having a bit of trouble finding and understanding the correct function to
make numeric vectors to feed the sunflowerplot function. I have 33k points
to show and I want to do better than the standard scatter plot.
I gather that I need two vectors (x and y) of the same count containing the
"center" value of each bin.
FYI - I have two pieces of data:

How to translate the 2D-density matrix (the output of bkde2D function) into matrix of datapoints' amounts?
It is known that function bkde2D (package "KernSmooth") returns a matrix of
density estimates over the mesh induced by x1 and x2. In Details it is
written that "... heights of the kernel, scaled by the bandwidths, at each
datapoint are summed. This sum, after a normalization, is the corresponding
fhat value in the output".
There are several questions:

problem saving gplot.hexbin using file save as pdf - "Error: invalid graphics state
I can save to png, TIFF and jpg but get an error "Error: invalid graphics
state" when trying to save as pdf and I have to restart R.
This happens when I add mtext lines.
There are a few other questions e.g. I want to move the mtext on side 1 to
the left, but that is the main issue for now.
I'm not using the ylab inside gplot.hexbin because it writes over the
numbers on the axis.

number plot symbol in scatterplot?
If I make a scatterplot and several (e.g. 5) points lie on top of each other
at a given x,y location I would like the plot symbol to be the number of
superimposed points (e.g. "5"). Could someone please tell me how to do this
in R? Thanks!
