I want to use contourLines() to get contour line coordinate vectors, but I don't want to make a plot. However contourLines() insists on opening a graphics device. Is there a way tell it not to do this? > version platform i686-pc-linux-gnu arch i686 os linux-gnu system i686, linux-gnu status Patched major 2 minor 1.0 year 2005 month 04 day 20 language R

Hi Folks, I have been using contour() to produce some contour plots (of a spatially-smooted density produced by kde2d()), with very satisfactory results. I now want access to the coordinates of the points on the contours, and it would seem that contour() does not return a value, so there is nothing from which these could be extracted. However, apparently contourLines() does, and it seems to be

A follow-up to my previous query. Say one of the results returned by contourLines() is C.W <- contourLines(....) Then C.W is a list of (in this case 28) lists, each of which is a list with components $level (a single number), $x (the x coords of the points on a contour at that level) and $y (the y coords). I can of course get these individually with, for the 5th one for instance,

I have a list of polygons generated by the contourLines() command (each object of the list is a list in itself with two objects: a vector of x values, and a vector of y values for each vertex). I wish to convert that list into a gpc.poly object of multiple contours. How do I do this? gpclib apparently has no method of coercing lists into the gpc.poly object type. As well, when I have a

Hi, I have not been able to find answers to these questions in the FAQs, manuals, or R-help archives. If answers are available somewhere, please direct me to them. 1.) Is there a way to convert a table (e.g. represented as a data frame) to a function, specifying which columns are input and which column is output? It would seem that this would be useful for plotting experimental results,

Full_Name: Dominik Heide Version: 2.3.1 OS: Linux (Suse 9.3) Submission from: (NULL) (134.76.220.200) The contour functions has sommewhere (I think in .../main/plot3d.c) a maximum number of line segments that is set using a define. The contour line in my data too long for this and therefore not correct analysed (I get the message 'contour(): circular/long seglist -- bug.report()!').

Hello everybody, I search a function which returns the contour of map with levels like contourLines, but I would like this function return the border of the map too, because the function contourLines cannot consider the corner of the map and it is not adapted to fill polygon after that. Thanks in advance Pierre Bruyer

Hello, Is it possible to draw level lines on the surface of a bivariate function? In the following example, to draw surface and levels lines for a multivariate normal law, I use persp, trans3d, contourLines and lines, but if the lines are correctly drawn, some parts of them are, of course, visible even if they are drawn on a non visible "face". Any suggestion to avoid this problem

Greetings all! I'm wanting to plot contours of a function, and I don't want to evaluate it at a dense grid of points (i.e. I don't want a huge array of values). Say I have a vector of x-values such as x <- 0.1*c(1:10), and the same for y <- 0.1*(0:10). I then evaluate a 10*10 matrix z of values of z = f(x,y). so I can then do CL <- contourLines(x,y,z) and get a list of

Considering the R function/plot shown below, I wonder whether it is possible to do the following changes: (1) Change the color of each point to be picked from list of colors according to its z-value. (The range should be from blue (z=0) to red (z=1).) The grid should then be omitted. [I have seen "terrain.colors", but don't know how to use it for this purpose.] (2) Add two lines to

I am using contour to draw contour lines onto a photo (jpeg) of a leaf on a white background. I have two problems: 1) The contour gets plotted at right angles to the jpeg image. I guess this is a problem of referencing the start and end points of the image matrix but I can't see how to over come this other than loading in a second image that has been rotated 90 degrees and plotting the

Hello List! I asked this before (with no solution), but maybe this time... I'm trying to project a surface to the XY under a 3d cloud using lattice. I can project contour lines following the code for fig 13.7 in Deepayan Sarkar's "Lattice, Multivariate Data Visualization with R", but it fails when I try to "color them in" using panel.levelplot. ?utilities.3d says there

Hi guys. The tex file which compile the following graphic has many problems. I don't know what's happening.

Hi, We are working on a product to analyze pcap files of VoIP calls. So far it does a reasonable job of analyzing the frequency distribution of packets in both directions, pointing out which direction packet loss / bad jitter occurs.  If you can trap the traffic on the outside and the inside of your Banana Pi and send me the pcap files, I would be happy to run it through our analyzer as

I'm trying to diagnose a bizarre problem in which the help files invoked from R are partially defective. help(), for instance, is missing the Description, Arguments and See Also sections; as are help files for other commands (see below). I've built 2.8.1, 2.10.1 and HEAD with the same results; do I need to set an environment or configuration variable? help

I’m in training, so I have to demonstrate something SIP related. I figure it would be cool to hack a call, hanging it up while in progress from outside Asterisk. Doing so will demonstrate use/knowledge of ARI, AMI, SIP, route-sets, UDP, etc. Practical value: zero :) Who knows, maybe this will have an actual application for someone someday. In practical terms I think building a proxy
