Hello, Is it possible to share a single host's Logical Volume among multiple local KVM guests which mount it read-only? I'm asking this because I have an idea to run multiple idential KVM guests (they all have exactly the same software installed on them), booting them from a shared local Logical Volume read-only root file system, or alternatively let them shar...

...all: My logistic regression model includes one qualitative and one quantitative predictor variable, aes <- glm(p.a ~ spp * log(light), family=binomial(link=logit)), where spp is abundance of 3 species and light is subcanopy light availability varying from 0 1. I want to test differences among levels of the quantitative variable at a value of x other than the current log(light)=0. I tried using I(log(light+.5)) but this caused serious lack of fit (AIC went from 1574 to 1656, and diagnostic plots demonstrated poor fit). How would create a model statement such that I test differences...

Dear list! I work with multiple Kruskal-Wallis test (kruskalmc, package pgirmess), which evaluates differences in medians among groups (5 groups). A result of a test is significant differences among some groups, while median values are the same for 4 groups (using tapply). Why? p.s.: number of samples in groups vary from 50 to 4900. Thanks to all, OV .

...ng matrix: m <- matrix(1:20, nrow = 10, ncol = 2) which looks like: [,1] [,2] [1,] 1 11 [2,] 2 12 [3,] 3 13 [4,] 4 14 [5,] 5 15 [6,] 6 16 [7,] 7 17 [8,] 8 18 [9,] 9 19 [10,] 10 20 Then, I want to remove randomly 2 rows among the ones where m[,1]<8 and m[,2]>12 I suppose the best way is to use the sample() function. I understand how to do it when I remove among any rows, but I have not been able to do it when I remove among specific rows only. What I could do is split the matrix into two matrices, one wit...

Hello, Is it possible to include information about phylogenetic relatedness among species (when species are replicates for each study within a meta-analysis) in a meta-anlaysis in the metafor package? Alternatively, I wonder if the method f Lajeunesse 2009 American Naturalist has been adopted in R in any fashion? Thanks, Scott Chamberlain [[alternative HTML version deleted]]

Hello R list, I need to compute empirical variograms using data from a large geographic area (~10^6 km2). Although I could not find a specific reference, I assume that both geoR and gstat calculate distances among data points assuming points are on a flat surface (using the Pythagorean Theorem). Because the location of my data is large and located near the pole, assuming that latitude and longitude are coordinates on a flat surface would introduce a -possibly large- bias in the empirical variogram esti...

Hello, I''ve been using cbq''s "weight" parameter to influence distribution of excess bandwidth among sibling classes. Does htb offer something similar? So far I think that - you either use priorities - then excess bandwidth is offered to higher priority classes first, the rest (if any) is distributed among lower priority classes - or you don''t use priorities - then excess bandwidth i...

hi I am having several pools of xcp with NFS shared storage as default SR on each pool and i want to do following in this arrangement -I want to share vdis among all pools, i.e. for example if I want to detach a vdi from a vm in pool-1 to a vm in pool-2. so is this possible to do so? vdi export is one of the solution but i want to do it seamlessly just like it happens within the same pool or without actually moving vdi over network because all the pool...

...atistician on Monday. I assess 4 statements from 90 subjects. Each of the 4 statements receives one of three responses (say -1, 0, or 1). I can use Cramer's V or Spearman correlations to assess the correlation between each pair of statements, but I am looking for a measure of coherence across/among all 4 statements. To me, this seems to be intraclass correlation. So I was wondering whether I can apply it here (specifically, ICC(2,1) or ICC(3,1)) or whether I should use an alternative procedure given that my responses are ordinal. I am grateful for your tips, Daniel -------------------------...

Dear all, I have created a subset from my dataset, which contains 6 variables. I need to make the correlation among all of them, possibly, without making it one by one. Is there any command that can permits me to do it directly for all of them in the same time? Thank you so much in advance. Andrea [[alternative HTML version deleted]]

Dear all users, I"d like to ask you how to make decision about colinearity among categorical independent variables when the model is multinomial logistic regression. Any help is appreciated, Niklas [[alternative HTML version deleted]]

This is a question about how to calculate similarities/distances among items that are classified by hierarchical attributes for the purpose of visualizing the relations among items by means of clustering, MDS, self-organizing maps, and so forth. I have a set of ~260 items that have been classified using two sets of hierarchically-organized codes on the basis of form...

I have data on the proportion of clutches experiencing different fates (e.g., 4 different sources of mortality) for 5 months . I need to test 1) if the overall proportion of these different fates is different over the entire study and 2) to see if there are monthly differences within (and among) fate types. Thus, I am pretty sure this is an RM analysis -( I measure the same quadrats each month). I am fine running the analysis in R - with the code below, however, there is no output for the among group variation...this is an important component - any ideas on how to solve this problem? I...

...ould be OK if I hadn't have to call it about 2000 times. This yields about 2 hours of processing. And I would like to use this script operationally; so that it should be run twice a day. It seems to me that the parallel processing option included in genoud() divides the task inside the function among the computers included in the cluster. On the other hand, my consecutive calls to genoud() are independent of each other, but all depend on objects stored in the R workspace. I think that communication time among computer for a 4 second task, repeated 2000 times should be slower that to divide the...

Hi, I''m wondering why SIGINT and SIGTERM both were chosen for the quick shutdown? I agree with SIGINT but not with SIGTERM. A lot of unix tools send SIGTERM as default (kill, runit among some) and it seems to be the standard way of telling a process to quit gracefully but not among Ruby people (there are a few other ruby processes behaving the same way). I just think it''s weird that the default command will exit without taking care of their current request. Also i'...
