I am doing some bibliometric analysis of interdisciplinarity using cluster analysis of co-authorship. I'd like to be able to specify the colour of individual authors in the labels to show a prior grouping by discipline (red for sociology authors, blue for economics authors, ..., that sort of thing). Is there any way of doing this sort of thing? I'm hoping for something like: h <-

Dear Friends, I have the very simple problem of needing to number observations in a data frame. After scratching the rest of my hair off my head without inspiration, I'm using a silly loop. I'm sure that there is a much more elegant and faster solution - can anyone help? Here is an example: my.data <- data.frame (person=c(1,1,1,1,2,2,3,3,3,3,3,3,3,4,4,4)) # now I want to number

Dear R-users Please excuse me if this topic has been covered before, but I was unable to find anything relevant by searching I am currently doing a comparison of two biological variables that have a highly significant linear relationship. I know that the p-value of linear regression is not so interesting in itself, but this particular value does raise a question. How does R calculate

Hi, Am newish to stats and R, so I certainly appreciate any help. Basically I have 50 inidividuals whom I have 6 photos each of their optic nerve head. I want to check that the orientation of the nerve head is consistent, ie the 6 replicates show minimal or preferably no rotation differences. I'll draw an arbitrary line between some blood vessels (same reference in each set of replicates) and

Dear all (not an R question per se, but given that the Real pRo's are all heRe I hope you foRgive) survival analyses assume that censoring is independent of hazard etc (eg, MASS 4th ed, pg. 354). Is there a standard test for this assumption? If there is not, what would you do to examine it empirically? (over and above some thinking about how censoring might be related to baseline factors).

I would like to get some idea of which R-packages are popular, and what R is used for in general. Are there any statistics available on which R packages are downloaded often, or is there something like a package-survey? Something similar to http://popcon.debian.org/ maybe? Any tips are welcome! ----- Jeroen Ooms * Dept. of Methodology and Statistics * Utrecht University Visit

I use R to create .eps graphics and then use oodraw to convert them to .emf versions. (One reason I do this is that OOo tends to re-size .eps files and I haven't found a way to stop it or change it once the graph is resized. .emf files are not distorted by OOo - fortunately.) I use a command like: > oodraw filename.eps & The gui opens and then I select .emf and do an export. I

This is a simple question but I cannot seem to find the answer. I have two vectors but with missing data and I want to add them together with the NA's being ignored. Clearly I need to get the NA ignored. na.action? I have done some searching and cannot get na.action to help. This must be a common enough issue that the answer is staring me in the face but I just don't see it. Simple

I am trying to setup a mail server using Postfix and Squirrelmail. The mail server will ONLY use webmail for access. I will not be using any email clients other than Squirrelmail. I've got the server working in a testing environment. Could people who are dovecot savy look over the config I have set? I've only included the directives that are enabled with no comments. I want a

Oh, hey, I'm more or less on the final stages of drafting the registration proposal that will be submitted to the IETF. If you have comments, suggestions, fixes, anything, this is it. https://trac.xiph.org/browser/experimental/ivo/drafts/draft-xiph-rfc3534bis.txt -Ivo

Hello all, I've been invited to do a presentation on Asterisk for the Ohio Linuxfest in Columbus this weekend (http://www.ohiolinux.org). Rough estimates are that nearly 500 people will be attending. I've been working on an outline for a couple of weeks and I would like to have some peer review of the information presented. I am going to have to cut down the content to make it fit in

Dear R, I'm looking for exact p-values for Spearman's rank correlation in the presence of ties. This is available in StatXact and SPSS, but I haven't yet found it in R. Has anyone implemented this? -- Paul H Artes Assist Prof, Ophth Vis Sci Dalhousie University, QEII Eye Care Centre Halifax, NS, CANADA

I would like to see if we can get patches posted to PR 8199 reviewed ASAP. These patches fix some problems with the lit tool and get the test suites working for me. I won't be able to contribute any code until this PR gets resolved. Patch #1 or Patch #3 on the PR both fix the problem. The difference in the patches is how ^ and $ are treated in substitution matching. Read the bug comments
