similar to: density plot for very large dataset

Dear All, I am researching financial market microstructure and have approx 4 x 10^7 multivariate 2D data samples which I have counted into a 250 x 390 bin matrix (frequency counted 2D histogram) in order to more efficiently manage the volume of data. I now wish to construct a smooth kernel density estimate (Gaussian kernel function) using this binned data. Does anyone in the R community know

Hi I've attached an example about something I want to do in R. This example was done in a Fortran application called ASGL. Here's an example in matplotlib http://matplotlib.sourceforge.net/examples/pylab_examples/hexbin_demo.html Basically, it's like a scatter plot, but have several additional things. One thing are the grids inside the graph, and the other is a density bar used

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: 1 - x axis - time in days of

How can perform logarithmic binning in the scatterplot? I could only take the log of the variables and plot them, but I am sure that is not the way. I have a very huge data, and would want to plot those high density scatterplots and code then with different colors for the bins/density. -- View this message in context:

Dear R-List, I've written some code to put measurement values at a position x and y in bins (xb and yb). It works, but I wonder if there isn't a function that would do what I do by hand in "# fill data in bins"? Here is the code: # data x <- c( 1.1, 1.5, 2.3, 2.5, 2.6, 2.9, 3.3, 3.5 ) y <- c( 6.3, 6.2, 5.9, 5.3, 5.4, 4.2, 4.8, 4.6 ) val <- c( 50, 58, 32, 14, 12,

Dear list, i just encountered a problem concerning the export of multiple plots. is it possible to merge several PNGs into one PDF document? i know that this could be easily done by pdf(), but the outcome of this is /way/ too huge (> 15 MB, four plots) and to my knowledge there's no way to compress PDFs directly in R. Hence the PNGs that are saved one at a time and afterwards merged by

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

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).

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

I tried to use: write.table() ----> Error in as.data.frame.default(x[[i]], optional = TRUE) : cannot coerce class 'structure("hexbin", package = "hexbin")' into a data.frame cat() ---> Error in cat(list(...), file, sep, fill,

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 # simulate data x <- rnorm(1000) y <-
