similar to: Get contour of a map

Dear friends of lme, After so many year with lme, I feel ashamed that I cannot get this to work. Maybe it's a syntax problem, but possibly a lack of understanding. We have growth curves of new dental bone that can well be modeled by a linear growth curve, for two different treatments and several subjects as random parameter. By definition, newbone is zero at t=0, so I tried to force the

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.

What can I do to UNDERSTAND why, periodically, I can't reach www.centos.org (but everyone else can)? Every few months, http://www.centos.org just drops off for me and for me only. It's not the web site, because I can reach it via a proxy (e.g., TOR browser bundle) and other tests show it to be alive (e.g., http://www.downforeveryoneorjustme.com/centos.org or

The web site for CentOS is not responding. I can ping it OK, but the web site is not responding to http requests from my browser. If the webmaster should happen to read this...

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

I am trying to use the levelplot function from a command file. Here is the code: library(sp) library(gstat) library(lattice) gatherData <- read.table("~/gather.txt", header = TRUE) grd = makegrid(gatherData$x, gatherData$y, cell.size = 5) k <- krige(z~x+y, ~x+y, data = gatherData, newdata = grd, nmax = 5) levelplot(var1.pred~x+y, k, aspect = mapasp(k), main = "Predicted

Hi, I need some help with making a function a bit more elegant. How would you all suggest avoiding the problem I've made myself below - I've written a function that creates a temporary matrix by subseting a larger one I assign it. I then call vectors from that matrix, add each item in the vector to create a cumulative vector for each factor, and then patch them all back together.

Dear R help, I've what I think is a fairly simple parallel problem, and am getting bogged down in documentation and packages for much more complex situations. I have a big matrix (30^5,5]. I have a function that will act on each row of that matrix sequentially and output the 'best' result from the whole matrix (it compares the result from each row to the last and keeps the

Hello, R experts, I tried to retrieve all biological process GO terms at level 3 starting "biological process" as level 1 using the code as bellows: 1 library(GO) 2 library(GOstats) 3 level2<-getGOChildren("GO:0008150")$"GO:0008150"$Children 4 for ( i in 1:length(level2)) { 5 level3 <- getGOChildren(level2[i])$level2[i]$Children 6 for ( j in

I'm a French developer (so I am sorry if my english is not perfect). I have a problem to smooth the contours of a map. I have a dataset with 3 columns, x, y and z, where x and y are the coordinates of my points and z is evaluate to a qualitative elevation and his representation is a set of colors, which is define by levels. The problem is the curve of my contour is so linear, and I would like

Hello, I have searched for documentation on the function contourLines's algorithm but cannot find a thing. I am about to submit a paper to a journal but cannot yet do so because I need to provide some reference for this function. Does anyone know what algorithm is used for this function? Thanks, Derek Lacoursiere -- View this message in context:

Hello R helpers, I would like to automate this code for many files of the same type. But I don´t know how to make it. In particular, i don´t know how to read many files each one as an r object with the name of the file. Then a for loop would be sufficient, right? Many thanks and a happy new year.

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 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

I came across a problem when one of our clients was not able to access any of the servers on our network. This person has never connected to us before and now for this first time was trying to do it from his home is Houston, TX using earthlink cable service provided by Time Warner. All this information, I think, is important because when I started examining my shorewall logs I found out

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,

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

Dear R experts, I wonder how can one input a string variable in multiple lines in a R script. I've seen solution to the command line continuation in the non-string situation (just continute at the new line). However, that doesn't work for strings because the new line character, "\n", is included in the resultant string. For example, if I type the following in a script:
