similar to: Clean up a scatterplot with too much data

Dear R users, I'm interested in a combination of a scatterplot and an image graph. I have two large vectors. Because in the scatterplot some areas are sparsely and others densely populated, I want to see the points, and I also want their color to be changed based on their density (similar to a heat map). Is there a function that can do that? Thank you, b.

Dear R users, do you know an easy way (other than star plot) of making several points laying one over another visible? Is it any simple way of increasing such "multipoint" symbols - or shifting their positions randomly to make several points in one place visible?

Hi, I want to draw a scatter plot with 1M and more points and save it as pdf. This makes the pdf file large. So i tried to save the file first as png and than convert it to pdf. This looks OK if printed but if viewed e.g. with acrobat as document figure the quality is bad. Anyone knows a way to reduce the size but keep the quality? /E -- Dipl. bio-chem.

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! Bill Simpson

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 List, I have an unusual problem concerning the Windows XP "Rotate" image explorer shell extension. I have a share called "Archives" defined with a number of sub-directories. Whilst I have read/write permission to all directories, I am unable to use the Windows XP "Rotate Clockwise" or "Rotate Counter Clockwise" image command on JPG's contained

Hello, I would like some help to plot a vertical line on a scatterplot build with hexbin package. I just need to plot a vertical line on the graph to mark a threshold value on x axis. It would be better if the parameter of the plot line function respect the x axis scale. Thanks, Rodrigo [[alternative HTML version deleted]]

Hello all, I'm trying to graph a scatterplot of a large (5,000 x,y coordinates) of data with the caveat that many of the data points overlap with each other (share the same x AND y coordinates). In using the usual "plot" command, > plot(education, xlab="etc", ylab="etc") it seems that the overlap of points is not shown in the graph. Namely, there are

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

Hi all! I'm trying to save an output of the HEXBIN process... is so much data (105k), and I need to export to an ASCII file. 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 <-

Dear list, I realised by chance when analysing a 1521862 ? 8 matrix that plotting was much faster when using "." as the argument of `pch'. I was just wondering if there were other ways to get this speed improvement: it is otherwise quite difficult to explore such big matrices, especially given that X11 redraws the plot whenever its window is covered/uncovered by another window, or

Hi, I'm wondering why when I use --size-only on the same file, except the modification time, rsync transfers the modification time? I was under the impression that --size-only caused rsync to transfer files based upon differences in the size of the file. For example: #cp Untitled.pdf Untitled-2.pdf #touch Untitled.pdf #rsync -ani --size-only Untitled.pdf Untitled-2.pdf .f..t......

Dear All i am trying to figure out the use of hexbin function in the hexbin package --can any one send me a working example of the same The > example(hexbin) ---option is of not much use Thanks Kind regards Ravi [[alternative HTML version deleted]]

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

I am interning in a computer science lab and I'm very new to R. The language basics are clear, but this particular problem isn't: I have a very large dataframe called "data" which holds data from Halo matches. I'm trying to analyze a certain window such that data$deaths>20 and data$deaths<=27. When I enter the line kills = data$kills[data$deaths>20] or any single

I have lots of data that I need to display, and I think hexbin would be good for it. However, I cannot load one of the requried packages associated with the hexbin package: > library(hexbin) Loading required package: colorspace Error in loadNamespace(package, c(which.lib.loc, lib.loc), keep.source = keep.source) : in 'colorspace' methods for export not found: [, coords, plot

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.
