Hello all, I'm attempting to conduct spatial analysis of trees within a plot. I want to see if the trees are spatially correlated to soil characteristics, say pH, or moisture content. I think one way to do it is with mpl, however, my soil characteristics were not taken at exactly the same locations as my trees and further, the vectors aren't the same length. I'm getting the

Hi. This will hopefully be readily understood but if not, bear with me. I have to do a repeated analysis (in spatstat) and want to batch file it. For each of my 'runs' certain variables change. At present I am manually specifying these changes and want to automate it if possible. Ok, I am creating an object which is comprised of 'levels' that are 'characters'. Further

Hello all. I am trying to create one figure, divided into 6 graphs/plots each with an inset sub-figure. I can use to layout command to generate one figure with one inset sub-figure, but cannot seem to do it for multiple figures on one page. I've tried a test with the following code: layout(matrix(c(1,2,3,4), nrow=2, byrow=TRUE)) plot(rnorm(10), rnorm(10)) plot(rnorm(10), rnorm(10))

Hello, I'm using library(spatstat) and trying to use ppp on my dataset. I get a segmentation error when I try to run it. Any suggestions? Code below ... Thanks, Suzanne --------------------------------------- dat <- read.delim(file="trees_R2.csv", sep=",", header=1) P16 <- (dat$Plot == "P1") | (dat$Plot == "P2") | (dat$Plot == "P3")

Hello, Can anyone tell me how to label individual bars on a barplot? I want to put an "*" or letter ABOVE the bar to denote statistical significance. Is this possible and how?

Hello all, I am trying to install the package 'spdep' and get the following error message when I invoke library(spdep) at the R prompt: Error in loadNamespace(i, c(lib.loc, .libPaths()), keep.source) There is no package called 'maptools' Error in library(spdep) : package/namespace load failed I get this if I try to install 'on the fly' AND if I download directly from

Hello, I'm working in spatstat and having difficulty with the ppp objects. I can get a ppp object for one set of data, but with the same code applied to a second data set (all I am changing is the field identifier), I get the following error message: Error in switch(w$type, rectangle={: internal error: some total scores are neither 0 nor 1 Any thoughts on what this means and how to correct

Dear R-users, I am exploring disease spread in trees. I have locations for diseased trees in 2004 and 2005 and want to know whether the patterns are independent. I would like to use both the 'gcross' and 'kcross' functions (in spatstat). I imported the data from two text files and created point objects using as.ppp. I then created a marked planar point pattern using ppp. I am

Hello, Is anyone out there doing nested anovas? I'm familiar with the notation to designate the nesting in SAS but can't seem to find any for R. How can I specify the nesting levels?

Hello. I think this is a simple problem. I have R running a program which generates variables that it 'remembers'. The trouble is that I've modified the file that it's generating these variables from but doesn't seem to realize that. When I type 'trees' - I get the same data set produced. I tried shutting R down and not saving the workspace, but when I open 'er

Hello, I still can't figure out why my users' passwords are expiring. Ever since we switched to LDAP, passwords expire every 14 days. Here is an example LDAP user entry: version: 1 # LDIF Export for: uid=sgoodrich,ou=Users,dc=trec,dc=us # Generated by phpLDAPadmin ( http://phpldapadmin.sourceforge.net/ ) on September 6, 2005 10:56 am # Server: TREC (localhost) # Search Scope: base #

Sorry Suzanne, but for this problem I did not have a solution! The Problem is, that WIN NT, start the Network with the LOGIN - Screen (one of the Security Mechanism). I've you try to enter the network request to the AUTOEXEC.BAT - File, it will not mountd // map one of the drives, because the network isn't start at this time! The next Point you could enter is after the Login - Screen

Hi r-users,   I really need help in fitting the t-copula.  I try to reproduce the example given by Jun Yan in “Enjoy the joy of copula” but I’m not sure how to correct the error based on the error message.  I tried so many ways but still could not get it working.   loglik.marg <- function(b, x) sum(dgamma(x, shape = b[1], scale = b[2], log = TRUE))   ctrl <- list(fnscale = -1)   #dat <-

Hi Everyone, I have a question regarding the construction of 3D graphs in 'R', BUT these graphs also need to illustrate movement (with time) of the prostate gland (using radiological techniques). I am not sure how to do this in 'R' although I'm sure there is some way of doing it. Below, I have copied and pasted some of the data with which I'm working on. The data

Hello, We are using Samba 3.0.14a-6, slapd 2.2.26-4 and smbldap-tools 0.9.1-2 on Debian. My users are complaining about warnings that their password is about to expire and that the are told "You do not have permission to change your password" when they try to change it. sambaAcctFlags includes the X flag which I thought meant "don't expire passwords."

(As a noob to R, this is my first posting - yes yes, groans all around...) I'm trying to extract certain rows from a data frame. I used the following to import data from a CSV txt file. data <- read.table(file="data.txt", header=TRUE) when I do this, my attempt to extract the data rows only from where the Station value equals 1? data.station1 <- data[data$Station == 1]

Hello! I want to plot a multitype point pattern called "new" in package spatstat. When I write plot(new) in the graphic window I can see a strech rectangle with a point inside, not the point pattern.If I write plot(new$x,new$y) the point pattern is plot ok.The problem is that I want do the density plots, quadrat count, etc and in these cases I can?t write density(new$x,new$y), I

This is an update on the current status of the relicensing, but also an opportunity to give feedback. Sorry it's rather long, but I think it's necessary to summarise the situation - there are probably list members who weren't even born at the start of the history of this! Xapian is currently licensed as GPLv2+, but isn't something we actually chose for Xapian, but rather due to a

This is a list with some libraries that I have been looking at. The idea is to discuss the advantages and disadvantages of adding some of these libraries to Xapian. If anyone knows another library that could be add to the list it would be great!
