Folks In trying to use lmer for a hierarchical model, I encountered the following message: Error in UseMethod("VarCorr") : no applicable method for 'VarCorr' applied to an object of class "mer" foo.mer <- lmer(y ~ TP + (TP|M),data=joe.q) > head(joe.q[,1:5]) TP M AB Trt y 1 1 Jan A NN 19.20002 2 1 Jan A NN 19.06378 3 1 Jan A NN

Group It's unlikely I'm trying this the best way, but I'm trying to create a data structure from elements like nNode = 2 nn = vector("list",nNode) nn[[1]] = list(Node = "1", Connect.up = c(NULL), Connect.down = c(2,3)) nn[[2]] = list(Node = "2", Connect.up = c(1), Connect.down = c(4,5)) .... #( and eventually many more nodes) NodeList =

I successfully used .Fortran to load and execute my fortran procedures under WinXP and 32 bit R. Alas, the same isn't true with my next Windows 7/64 machine, R 2.14.1 (64 bit) and the gnu gfortran (64) compiler (mingw64 v. 4.6.1). Though I'm able to compile the routines from the command line using gfortran '...', .Fortran('foo2') results in an error saying the Fortran

Nick, I've also made colors transparent by pasting the hex equivalent of, say, 0.3*256 = 76.9 to the hex color code. e.q. for black it might be "#0000004d" and the 4d is 77 in hex. That way you don't need to convert back and forth so much. If col is "#000000" the transparent version is tcol <- paste0(col,"4d") This would work in one step on a whole

I'm dipping my toe in graph theory and found that R has a rich collection of network and graph tools. However, I can't seem to put my finger on the solution to my problem. There are several procedures available in R for finding a shortest path along edges between vertices based on the cost of traversing a link, but my problem is to find _all_ of the _longest _paths between vertices

Good Afternoon R Community, I am working on plotting behavior codes over short durations of time (a few seconds at a time over 1-2 hrs). I am utilizing as.POSIXct to store the time. I wanted to make a quasi time line using these time. I utilized the segments function to represent these times. However the segments rounds off at the ends and does not have the crisp look I need for my purposes.

Dear all; Thank you for your reply. David has explained an interesting method. David I have DEM file of the region and I have extracted the xyz data from that. Also I can extract bathymetry data as xyz file. I have calculated the storage (volume) of reservoir at the current elevation. But the method I have used to calculate the volume is different from your method. I have crop DEM by the reservoir

Water engineer here. The standard approach is to 1) get the storage vs. elevation data from the designers of the reservoir or, barring that, 2) get the bathymetry data from USBR or state DWR, or, if available, get the DEM data from USGS if the survey was done before the reservoir was built or 3) get a boat+sonar with GPS? +lots of time and survey the bottom elevation yourself. Put the xyz

Hi all, it there any possibility to draw colored shading lines of a polygon plot? E.g. plot(polygon_object,col="red",density=10,angle=45) produces only black shading lines within the polygon. With many thanks for any hint Albrecht

I want to plot a large number of line segments, with a color associated with each line segment (I'm actually plotting a function of the edges of a 2d graph, and I want to use color to indicate the level of the function.) I originally thought I could use lines, but lines puts all its lines in one color (from help(lines), "col: color to use. This can be vector of length greater than one,

Dear r-help, I need to draw xyplot() graphs with several regression lines: one line for the whole range of x (the variable on the horizontal axis) and two additional lines for subranges of x. Is it possible to make first regression line (panel.lmline(x,y,...);) to be drawn on the whole graph and regression lines of the subsets to be drawn only over their subsets? I have defined

Hello, I've a question concerning the display of interval data. A sample dataset where X is an interval between Xa and Xb which should be displayed: Y=c(15,14,23,18,19,9,19,13) Xa=c(17,22,21,18,19,25,8,19) Xb=c(22,22,29,34,19,26,17,22) X = (Xa+Xb)/2 It's easily possible to plot the mean of the interval like: plot(X,Y) afterwards I can create lines for the interval with:

Hi. I need a very short piece of help regarding colouring segments plotted on a graph. When I am plotting segments for the graph, I am using "red" and "darkgreen for the values "1" and "2" respectively. Heres the relevant line of code in R: + col = c("red", "darkgreen")[line.colour.value]) I just need to extend this to refer to a larger

Hello Everybody, I'm trying to plot(x,y) using different colors. I have to cut (x,y) into sub intervals. And I want to plot this sub intervals using colors. But infortunally I don't know how to do this with R. Can any body help me please? My code is looking like : x<-c(tvar[1:t0],tvar[t0:(ts)],tvar[ts:n]) F<-c(var[1:t0],var[t0:(ts)],var[ts:n]) plot(x,F,xlab="Zeit

Hello, I am trying to wrap my head around the coordinates systems associated with the layout() function ...with the end goal of simply drawing a decorative line in the upper margin of my figure, which is composed of three plots. My output is defined as this: ---------------------------------------------------------------------------- postscript("out.ps", horizontal=FALSE,

Dear lattice wizards, I am trying to figure out how to plot predicted values in xyplot, where the intercept, but not the slope, varies among conditioning factor levels. I am sure it involves the groups, but I have been unsuccessful in my search in Pinhiero and Bate, in the help files, or in the archive, or in my attempts on my own. My example follows: FACT is a factor with levels a,b,c

Im using an FXText and want to change the color or background color of individual lines. Is there a way to do it? I see methods called xxxxStyledText but cant find anything about them. THis is fx from the 1.8.1 build 11 windows installer Thanks Paul

I'm having a problem with rgl.snapshot. If I run the following code *once* and *once only*, all is well. data(trees) attach(trees) plot3d(Height, Girth, Volume, type='s') rgl.snapshot("/home/user/pic.png", fmt="png", top=TRUE ) And the pic.png looks right. But if I try to rerun rgl.snapshot anytime again in this session, the file pic.png still outputs but is

Hi, I want to format my axis in my persp3d plot. With my data, which I attached I created a persp3d plot with the following code, which I summarized from different code snippets I found: library(rugarch)library(rgl)library(fGarch)fd <-as.data.frame(modelfit,which ='density')color <-rgb(85,141,85,maxColorValue=255)x <-seq(-0.2,0.2,length=100)y <-c(1:2318)f

I suggest a simple enhancement to segments() and arrows() to facilitate drawing horizontal and vertical segments -- set default values for the second x and y arguments equal to the first set. This is handy, especially when the expressions for coordinates are long. Compare: Segments: < function (x0, y0, x1 = x0, y1 = y0, col = par("fg"), lty = par("lty"), --- > function
