Hi All, I am having trouble installing the sm package, and only the sm package. My box is RedHat 7.3 on a PIV. Readline 4.3-3 is installed (suited for RH 8, but same error under readline 4.2 for RH 7.3), but it seems to be looking for the readline library in the wrong directory. Will installing readline 4.1 do the trick? What else could be done? Rohan Sadler [root at rsadler R]# R CMD

Hi all, I get two different results when using sum() and the switch na.rm. The result is correct when na.rm=FALSE. Linux Redhat 7.3, R version 1.6.1. I've had no luck searching the mail archives, so I was hoping somebody could explain/check this one for me. I will need to apply the function to missing data, simple as it is. Code: x<-matrix(runif(20,0,5)%/%1,4,5) # random matrix

Hi, We have been running R ver 1.4.1 on a redhat linux (7.1)cluster without problem for quit some time. Now, some user wanted me to install version 1.6.1, and it compiled fine, but it crashes with "segmentation fault" when you run it. I used gcc296 (default) for compiling, Should I change compiler or is there some other thing I could do to avoid this problem. Regards Per-Anders

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

Dear R-Listers, I have spatial data on an equidistant rectangular grid, similar to topographic data. I know that there are quite a few R-packages or base functions that provide nice iso-contours plot, but I don't want a plot, just the smoothed isocontour line of ONE level (e.g. 10 mm). Data sets are large, so it would be preferable if the availability of regular grid data could be exploited,

Dear All, This is a question to sound out possibilities. I am with the Faculty of Natural and Agricultural Sciences at the University of Western Australia, representing a few of the more statistically minded in the faculty. Essentially, there have been problems in the past with software support, changing over statistical software, and paying lots of money for it. In R you have an advanced

Hi I am a programming pleb, however I would like to learn how to write my own functions and methods. Can anyone suggest a good place to start teaching myself, readings or other?

Hello all, I''ve been searching through the archives and the internet for a while now, and can''t seem to find anything that helps me out. I hope you don''t my posting this to both xen-users and linux-lvm simultaneously, but i figured it''d help keep the solution in one place... even though it''ll be the same across two places... Anyways: My setup is this:

Hi List, as I''m a real beginner I would be pleased if someone can answer a maybe simple question. I''m looking for a virtaul server system to be used by diffrent entities. As I heard from other solutions there are often (at least small) security problems. Now I would like to know if it''s (at least theoretical possible) that one user from domU_a can access domU_b or

I am currently running three different machines with Xen and have running DomU''s on server 1 and server 2. I trying to run a new instance of Windows 2000 on Server 2 (I''ll include the specs below), but every time the install gets to "registering components" portion, the installation restarts. I try the install on my workstation and it does the same thing.

Next week are going to start using rsync "live" to mirror our primary and secondary web servers. I am still trying to iron out a couple of bugs, any help would be much apprecitated. Here is my rsync.conf file on my primary web server ############################ use chroot = no max connections = 5 syslog facility = local3 [www] path = /www comment = Web Directory hosts

Hello, Is it possible to add some static entries to the WINS database? We would like to add a few (logon-)server entries to it, when wins starts up. Why? We have several Samba servers who act as logon server on different subnets for different domains. Each logon server also acts as a local WINS server. It doesn't seem possible, not even with the options 'remote announce' or

Hi, I was wondering if anybody could give me some advice about the best way to go about seperating client users from internal users. I''m building an application which will give our clients a subdomain with several user accounts which they can use to check the status of their project with us, request services etc. User accounts should not be shared across subdomains. As well as these

Hello, I have a simple problem (checked the archives and the appropriate help pages, to no avail). I want to creat a vector that is length(2000). The vector is to consist of two strings( "std" and "dev") with 1760 "std"s and 240 "dev"s. Furthermore, for each element of the vector, i want the selection of one of the strings to be approx. random. The

Hi all, I have a Samba PDC setup and i was wondering if anyone knows how i can force the users to change passwords ever x days. My network consists of windows type machines as was as linux based machines. Any help would greatly be apprecitated.

Hi all, The suggestions were great. However, after installing readline-devel I had to install ncurses-devel before getting sm to work. Can this be put into the RH 7.3 Readme when downloading R rpms (and other distbns like Mandrake where there may be a similar problem)? Thanks for your help.

Hi all, I wish to implement various landscape ecology measures through R, such as: box counting dimension; twist number statistics; contagion and lacuniarity indices; angular second moment; adjacency measures; dominance indices; etc ... Some of the measures can be applied to shape analysis and classification. Is anyone implementing any of these measures? If so I would like to contribute and

The Institute for Social Research (ISR) and its Statistical Consulting Service (SCS) at York University are pleased to announce our Summer Program In Data Analysis (SPIDA) for 2012. The Program runs from May 24th to June 1st, 2012.This year?s Program focuses on the theory and practice of linear models and mixed [or multilevel] models, as they are applied to hierarchical and longitudinal data.

We were caught out recently attempting to use tapply to get a table of weighted means. This gives the wrong answer (or, more correctly, not the answer we were expecting), as the following example shows: R> x <- 1:10 #some data R> w <- c(1:5,5:1) #weights R> id <- rep(1:2,rep(5,2)) #id values R> weighted.mean(x[id==1],w[id==1]) #Weighted mean of x in group 1 [1] 3.666667
