search for: hist2d

Dear R users, I am just starting with R (v. 1.0.0) and I use Vehables & Ripley's MASS book for examples. In the intro session, there is an example of a 2D histogram on an 8x8 grid: x <- rnorm(1000) y <- rnorm(1000) contour(hist2d(x,y,,,8,8)) R complains: Error in contour(hist2d(x, y, , , 8, 8)) : couldn't find function "hist2d" I looked for hist2d() in the manual (including the latest development version), but didn't find it. Is there such a function or a suitable substitute? Thank you! Aleksey...

I'd like to use the hist2d function. What library contains it? Thanks! Simon Firestone Economist, Fair Lending Enforcement Division of Consumer and Community Affairs Federal Reserve Board Washington, DC 20551 simon.b.firestone@frb.gov (202) 785-6056 [[alternative HTML version deleted]]

I created a 2d histogram using gplots' hist2d: hist2d(x,y, freq=TRUE, nbins=50, col = c("white",heat.colors(256))) rug(x, side=1) rug(y, side=2) box() Now I would like to reverse the Y-axis, tried to use ylim=rev(range(1:400)) but seems not to work. Any ideas? Ralf

I am plotting a heatmap using the hist2d function: require("gplots") x <- rnorm(2000) y <- rnorm(2000) hist2d(x, y, freq=TRUE, nbins=50, col = c("white",heat.colors(256))) However, I would like to flip the vertical y axis so that the upper left corner serves as the y-origin. How can I do that? Ralf

The following code produces a heatmap based on normalized data. I would like to mirror x and y axis for this plot. Any idea how to do that? require("gplots") x <- rnorm(500) y <- rnorm(500) hist2d(x, y, freq=TRUE, nbins=50, col = c("white",heat.colors(256))) Best, Ralf

Hello, I have created two histograms with: hist2d(gps2, nbins=200, col = c("white",heat.colors(16))) Both of them have the same range and the same number of bins. Now I would like to compare them bin by bin and plot the results. Could someone please tell me how to do that. I searched the man pages and the web, but couldn't find anyt...

Hi all, I would like to plot one data set as a 2d histogram and another one as a contour. I can do it separately with the "hist2d" and "contour" functions, but I wonder if there is a way to combine these two plots into a single one (the ranges of the two plots are the same). Any suggestions? Thanks, Anna [[alternative HTML version deleted]]

...ne, I hope this question is beyond "read the manual". My task is simple, just to plot the following, but the plot in the middle should be a filled.contour plot: http://gallery.r-enthusiasts.com/graph/Scatterplot_with_marginal_histograms_78 Background: I prefer filled.contour rather than hist2d. Because, I could use kernel smooth, so the plot for discrete data won't be too ugly. I also tried image() and then contour(), but the number on contour is not clear and no indication about the color. My problem: in filled.contour function, it uses layout() for filledcontour() plot and rect()...

I discover last week the R software statistics programm, I have a small questions, When we generate a bivariate normal distribution is it possible to plot the generate distribution. The second one if there is a code to generate a bivariate student distribution. If yes i would ask you gratefully a help. Thank you very much

...to draw/analyze silicon wafer maps? Here are some examples http://www.java2s.com/Code/Java/Chart/JFreeChartWaferMapChartDemo.htm http://dp.pdf.com/site/products/wafermap/binmap.html I've google'd and searched CRAN with no luck. It seems possible for R, given the hexbin and hist2d graphs I saw at the Graph gallery. Thanks, Sam [[alternative HTML version deleted]]

Hi ! I want to find the surface the interpolates a 2D histogram, that I have generated with hist2d. I don't want to make a fit, but simply an interpolation. Which function have I to use to do this ?
