Hi, I have a (correlation) matrix and I want to select a subset of its cells depending on the combination of their column and row names. This illustrates my problem: mtrx <- matrix(c(1,2,3,4,5,6,7,8,9), nrow=3, ncol=3, dimnames = list(c('c132','c432', 'c233'), c('r132','r233', 'r432')))> mtrx r132 r233 r432c132 1 4 7c432 2

Dear R Help Community, I have a question and an answer (based on reading this forum and online research), but I though I should share both since probably there's a much better way to go about my solution. My question is specifically about how to best visualise multiple response contingency tables. What I mean by 'multiple response' is that the total number of responses per row of a

To anyone who can help, I have two stupid questions, and one fairly intelligent question Stupid question (1): is there an R function to calculate a factorial of a number? That is...is there a function g(.) such that g(3) = 6, g(4) = 24, g(6) = 720, etc? Stupid question (2): how do you extract the estimated covariance matrix of the random effects in an lme object? Intelligent question

ok, try it like this.   hosts allow = 127.0.0.1 192.168.1.

Hi again, I was contemplating the solution using base 3: set.seed(3) mat2 <- matrix(sample(0:2, 15, replace=T), 5, 3) Extracting the line numbers is simple: bases <- c(3, 3, 3)^(2:0) # or just 3^(2:0) colSums(apply(mat2, 1, function(x) x*bases)) + 1 [1] 7 23 25 8 1 The problem is sometimes the columns have different number of levels, as in: mat1 <- expand.grid(0:2, 0:2,

Hello All, I have a question regarding how glmmPQL should be specified. Which of these two is correct? summary(fm.3 <- glmmPQL(cbind(response, 100 - response) ~ expt, data = data.1, random = ~ 1 | subject, family = binomial)) summary(fm.4 <- glmmPQL(response ~ expt, data = data.2, random = ~ 1 | subject, family =

I added a hosts deny line to above and denied one specific ip address. I then deleted that line but added hosts allow and made this equal to any ip address within previous "denied ip address's subnet. However, the afore-mentioned ip was still denied and I had to allow it individually. Can anyone tell me why. Thanks Bernadette McCluskey Ops/Comms Administrator GMB National

Hi, I''ve collected together a bunch of XCP-related project suggestions and stuck them on the xen wiki: http://wiki.xensource.com/xenwiki/XAPI_project_suggestions The main idea is that new people who want to work on XCP can use this list for inspiration... each idea has a rough guesstimate of size/ knowledge required/ impact and an initial first contact (who either suggested the idea

Does anyone have a guesstimate of how many active Asterisk installations there are? Sorry this is off topic, need it for a customer proposal and they need comfort on stability. A count of the downloads from Digium would be a good start but I couldn't find this anywhere with Google. Feedback from anyone who may know near actual data would be appreciated rather than simply guessing,

Hi, Been having a look at the roadmap on the wiki for Dovecot 2.0 and I was wondering how that's progressing? Are you able to offer a guesstimate on how far it is from stable Timo? Just asking because we're moving to new servers soon and I'm considering using the opportunity to switch from Dovecot/Maildrop/Maildir to Dovecot/deliver/mdbox if 2.0 is likely to be reasonably safe to use

Dear R-helpers, I'm trying to develop a function which specifies all possible expressions that can be formed using a certain number of variables. For example, with three variables A, B and C we can have - presence/absence of A; B and C - presence/absence of combinations of two of them - presence/absence of all three A B C 1 0 2 1 3 0 4 1 5 0 6 1

Dear all, I have a 10 columns matrix which has 2^10=1024 unique rows, with values 0 and 1. What I would like to do is a little complicated; in a simple statement, for a subset (say 1000 rows) I want to perform pairwise comparisons between all rows, find out which rows differ by only one value, replace that value by "x", get rid of the comparisons that differ by more than one value

Hi, I am a new user of R using R 2.8.1 in windows 2003. I have a csv file with single column which contain the 30,000 students names. There were typo errors while entering this student names. The actual list of names is < 1000. However we dont have that list for keyword search. I am interested in grouping/cluster these names as those which are similar letter to letter. Are there any
