similar to: 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

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 anything. Thank you very much. Phil

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

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

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) #toy

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

I am having difficulty installing packages. For example, here I have tried to install "gplots" but to no avail. I have tried multiple mirrors and different packages (errbar) but after installation I seem to be unable to access any of the commands or help pages. I am a little concerned about the 'lib' missing message but this has been present for previous successful package

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]]

Thanks Thomas and Marc that is what I was looking for. -Jason The DESCRIPTION file for a package lists the license; this is also given in the CRAN entry for each package. -thomas Marc Schwartz <MSchwartz@MedAnalytics.com> 03/30/2004 09:02 AM Please respond to MSchwartz To: Jason.L.Higbee@stls.frb.org cc: R-Help

I would like to run the Federal Reserves econometric model on open source software - they sent me the specifications for the model and what is neccessary to run the model on TROLL (which is a commercially available econometric software) I am looking into the feasability of doing this and whether or not R is the right tool - I would like to discuss the idea with someone who is familiar with this

Hi everyone, 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

R: Is there a reason why there isn't a Windows Binary version of RQuantlib on CRAN? Usually when there is no binary, I just source the source code, but this one appears to have various calls and methods and things like that so I'm hesitant to do so. I know there has been a big discussion on why Rmetrics doesn't have source for unix/linux, but that isn't on CRAN. Through

Hello R-Users! Does anyone know of a package 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.

R: I got a warning message when running the cor.test function using both Spearman and Kendall rank correlations saying that the p-value may be incorrect due to ties in the data. My data has 35 obs and one series has 6 pairs of ties. Does anyone know if this would likely have a great effect on the p-values calculated.. The values look good; tau = -0.68 with p-value = 8e-9 and rho = =0.84

R: I have a program that runs a For loop for days and I need to (if possible) pause the program. Any ideas on how to do that? If I use stop, how certain can I be that all the statements executed in the previous iteration of the for loop?

I'd like to fit an ARMA(1,1) model to some data (Federal Reserve Bank interest rates) that looks like: ... 30JUN2006, 5.05 03JUL2006, 5.25 04JUL2006, N &lt;---- here! 05JUL2006, 5.25 ... One problem is that holidays have that "N" for their data. As a test, I tried fitting ARMA(1,1) with and without the holidays deleted. In other words, I fit the above data

Alle, We have recently had one of our office servers go south. The hardware was an Intel SDS2 motherboard (EATX), Dual Intel PIII 1.4GHz FC-PGA2-L2 512KB, 3GB (6x512MB) 168 pin DIMM, SDRAM 133MHz/PC-133-ECC with 1x3Ware 7006-2 and 2x3Ware 7506-4LP RAID controllers. The OS was RHEL3. Apparently, according to the beep codes, there has been an FRB failure. I've migrated most of the
