hello, all. one of my students is having an issue with the pie & legend function. this is her code. (below) it works just fine for me. her error is "plot.new has not been called yet". i know this means her pie chart is coming up blank so the legend will not work. according to ?graphics this package *is* supposed to handle these functionalities. however, when i tried to

Hi all, I am trying to produce some panels with dots in an X/Y plane where the diameter of the dots indicates a Z value (like e.g. earthquake maps where dot sizes indicate magnitudes and X/Y the location). This works fine with xyplot, e.g.: xyplot(1:3~1:3,cex=1:3,pch=16) However, when I do this with a panel variable, e.g.: x<-rep(1:3,5) y <- rep(1:3,5) sz <- rep(1:5,each=3) grp

Hi there, sorry for troubling everybody once again, I've got a problem rewriting Sarkar's function for rewriting the tick locations in a logaritmic way (s. http://lmdvr.r-forge.r-project.org/code/Chapter08.R): His example works for log 2 but I need log e (natural logarithm). My problem is that if I replace 2 with "e" (using paste()), I get the error message that the location

...aved file after I run the program. But if I use the function "plot" to get other simply figures, it can work. So I want to ask how I can get the saved figures by using "xyplot". The following is a simple example about my program: library(lattice) require(stats) ## Tonga Trench Earthquakes Depth <- equal.count(quakes$depth, number=8, overlap=.1) for (i in 1:5) { filename=paste("fig",i,".pdf",sep="") pdf(filename,width=6.5,height=4.5) xyplot(lat ~ long | Depth, data = quakes) graphics.off() } # I cannot open the pdf files. Buf if I try: for (i in 1:5)...

...but got no response. Can select.spatial() be used in an existing spplot? I have tried selecting points (eq) from a plot generated from sp. However, when I invoke select.spatial(eq). It generates only the points without the background containing the faults. I need the background to select which earthquakes coalesce on which fault. Is there an alternative? eq.pts<-list("sp.points",eq, col="blue", lwd=0.5, pch = 4) spplot(faults,"Dip", xlim = c(110000,120000), ylim = c(3760000,3890000), sp.layout=list(eq.pts), col = heat.colors(3)) select.s...

Hi, I am a student of Earthquake Engineering, and am new to R. Currently I try to run nonlinear regression analysis by R. My data has three variables: X, Y, and Z. Z is a function of (X, Y). My R script is as below. rm(list=ls()) # read in data Alldata <- read.table("~/Documents/R/Wu_data.dat", header=TRUE) # assign variables Z <- Wu[[1]] # N1,60 X <- Wu[[2]]

hello I have spatial data which contain number of landslide presence cells with respect to landslide predictors and number of landslide absence cells with respect to same predictors. predictors are essentially categorical data. I tried logistic regression. But because of providing interaction capability of predictors, I want to use log-linear method. I hesitate the way I should use

Since we've been debating the merits of start or end timestamping... i'm curious why the page doesn't have both stamps ? That would solve the problems for all parties wouldn't it ? It's not like the overhead is huge... less than 0.1%... so on the average audio file thats 5 megs.... it's a 5k increase, which pretty much insignificant. Even on a 1gig video file it's

Today, I had a tragic hard drive crash. I hadn''t updated anything to SVN in two weeks. I''m posting this here as a reminder to my beloved Rails community. Everyone, right now..... make a backup of your rails work. Make sure its on two disks. Many of you already do that automatically, but just make sure its working. Two near-release rails plugins were lost in the tragic crash

We're trying to setup 3 PRDM partitions (VMware) across 2 nodes. As long as only one is configured in cluster.conf, there's not problem. As soon as we try to use 2 or more we get issues. It looks the same as bug 636: http://oss.oracle.com/bugzilla/show_bug.cgi?id=636 I posted my cluster.conf and command line results there. I'm including them here in the hopes that someone on this

I have been using delay() quite successfully to 'load on reference' some large data files (earthquake catalogues). One minor difficulty I have not been able to overcome is that upon first reference, the data set is loaded into memory as expected, but also remains as a permanent object in the user's environment, instead of appearing to be only in the library from which it was loaded.
