Hello, Can anyone offer any insight on graphing classification dendrograms with the nodes marked? plot(tree()) produces a nice tree structure but there's no acccompanying text. Thanks, D S.

Dear all, I'd like to draw a color key beside a graph drawn with xyplot (lattice library). I am aware of the draw.colorkey function (grid library) but don't know how to handle it. Any hint would be appreciated. Renaud -- Dr Renaud Lancelot, v?t?rinaire CIRAD, D?partement Elevage et M?decine V?t?rinaire (CIRAD-Emvt) Programme Productions Animales

I'd like to change the way plot.hclust displays an hclust object. Here's a description of how it's done now, from the R documentation of hclust: In hierarchical cluster displays, a decision is needed at each merge to specify which subtree should go on the left and which on the right. Since, for n observations there are n-1 merges, there are 2^{(n-1)} possible

I have a collection of SAS code that helps people review large amounts of data on a regular basis. It does this by using SAS's proc gplot with a "by" statement to prepare as many as 400 (yes, 400) separate graphs. The code is run on a remote unix host, and displayed on the reviewer's local desktop using X11 and SAS's display manager. The process is initiated from a web

Hi, Could any one point me to the projection, and parameters if necessary, that would show each country/continent with it's area accurately refelcted on the plot? E.g. aitoff vs. albers vs. bonne vs. cylequalearea vs. guyou - they don't all look the same to mee but some of the documentations suggests they are equal area? Of course this isn't my field, so I am largely guessing and am

Dear all, I am interested in plotting maps visualizing spatial statistics in an aggregated fashion, according to administrative boundaries. More specifically, I have fitted a cross-section model on data regarding Italian "counties" (province, for Italian readers) and I would like to visualize residual behavior on a map, in order to have a first assessment of their spatial

I'm using R 1.4.1 under Windows 2000 and am experiencing difficulty installing a package. I've included an example output using Rcmd build, but the same problem occurs with Rcmd check and Rcmd INSTALL. The error (make[1]: /bin/sh.exe: Command not found) is not a new one - it's referenced in readme.packages among other locations. I've placed a copy of sh.exe in C:\bin, but it

Dear all, 1. How can I compute the intersecting area between 2 polygons ? 2. I have polygons with coordinates in decimal degrees (i.e. 13 deg 30 min = 13.5 decimal degrees). I want to compute their area and get the results in square meters or square kiometers. Can anyone give me a conversion coefficient or a pointer where I can find this information (sorry for this off topic question) ? Thanks

So I have 2 sets of data - a training data set and a test data set. I've been doing the analysis on the training data set and then using predict and feeding the test data through that. There are 114 rows in the training data and 117 in the test data and 1024 columns in both. It's actually the same set of data split into two. The rows are made of 5 different numbers. They do represent

I am working through Tom Minka's lectures on Data Mining and am now on Day 32. The following is the link: http://alumni.media.mit.edu/~tpminka/courses/36-350.2001/lectures/day32/ In order to use the functions cited I followed the instructions as follows: Installed tree package from CRAN mirror (Ca-1) Downloaded and sourced the file "tree.r" Downloaded the function

I am trying to make a decision tree using rpart. The function runs very quickly considering the size of the data (1742, 163). When I call the summary command I get this: > summary(bookings.cart) Call: rpart(formula = totalRev ~ ., data = bookings, method = "class") n=1741 (1 observation deleted due to missingness) CP nsplit rel error 1 0 0 1 Error in yval[, 1] :

I am having trouble getting smooth-appearing curves in figures produced as windows metafiles using R (R-1.1.1 on Windows 98). When I import them into a word processor (either MS Word 97, or WordPerfect 9.0), the figures appear only slightly bumpy on screen, but when printed, there is a clear jaggedness reminiscent of aliasing. Is there a fix for this (if the answer is "upgrade to 1.2",

I am performing a binary classification using a classification tree. Ironically, the data themselves are 2483 tree (real biological ones) locations as described by a suite of environmental variables (slope, soil moisture, radiation load, etc). I want to separate them from an equal number of random points. Doing eda on the data shows that there is substantial difference between the tree and random

Hi this is my first post. I am trying to run a simulation for a computer playing Von Neumann poker and adjusting it's expectation of an opponent's behavior according to how the opponent plays. This program involves random generation of "hands" and shifting of parameters. However, when I run the code, no errors come up, but the program doesn't do anything. Could someone

I use knncat to make a predictive model and get misclass rate > knncat.m<-knncat(training.new,k=c(10,20),classcol=5) > knncat.m Training set misclass rate: 36.88% then I try to calculate prediction accuracy by the following: > pr.knncat.train <- predict (knncat.m,training.new,training.new,train.classcol=5,newdata.classcol=5) > tb.knncat.train <-table (pr.knncat.train,

Simple question: is it true that polygon (x, y, col=vec, border=vec, ...) will cycle through the vec colors for fills but not for the border colors when sending multiple polygons? thanks, Denis White US EPA, 200 SW 35th St, Corvallis, Oregon, 97333 USA voice: 541.754.4476, email: white.denis at epa.gov web: www.epa.gov/wed/pages/staff/white/

We are trying to implement Breiman's one standard deviation pruning rule for tree models. I have run into a problem with predict.tree. This bit of R code, a skeleton for a cross-validation process, library (tree) dat <- data.frame (matrix (runif (3*100), nrow=100, ncol=3)) a.dat <- dat[1:50,] b.dat <- dat[51:100,] a.tree <- tree (a.dat) b.pred <- predict.tree (a.tree,

Dear all, I stumbled over a problem recently when trying to use srt with text() on a windows device. What I intended to do was to plot a simple regression line, and to rotate a piece of text such that the text has the same angle as the regression line. However, the text is always plotted in a slightly wrong angle: #### x=1:10 #create arbitrary x and y values y=x*2-rnorm(1:10)

I'm adding a couple of vignettes to an existing package. When I make a change to the sweave file, and run the check command, c:\conifers\trunk>R CMD check rconifers I get the following message(s) in the 00check.log file: * checking for unstated dependencies in vignettes ...
