similar to: discrepancy in fisher exact test between R and wiki formula

For a pedagogical purpose, I was trying to show how the formula for a simple regression line (~1+x) could be crossed with a factor (~1:group + x:group) to fit separate regressions by group. For example: set.seed(201108) dat <- data.frame(x=1:15, y=1:15+rnorm(15), group = sample(c('A','B'), size=15, replace=TRUE)) m1 <- lm(y~ 1 + x, data=dat)

Hi, I am apparently not understanding some nuance about either the use of subset or more likely my ability to test for a numerical match using '='. Which is it? Thanks in advance. I've read a data file, reshaped it and then created MyResults by keeping only lines where the value column is greater than 0. So far so good. The data in MyResults looks good to me by eye. The

hi all... i have what seems a simple question regarding subshares, for lack of a better term... say i have a share with specific user/group permissions and a directory inside the share that i would like to add different user/group permissions... this is an example of my smb.conf file to illustrate [driveA] path = /samba/driveA browseable = Yes writeable = Yes valid users = PDC+groupA force group

Everyone, I have finally resolved the new heartburn 3.0.24 on Ubuntu Feisty was giving me and have stumbled upon some information that might help others out there. I was seeing problems with ACL entries getting mangled and disappearing, Excel making files read only and extended attributes doing bizarre things. The solution revolved around what appears to be a change in how ACLs are managed.

Hi, Scenario :- User A belongs primarily to GroupA and secondary to GroupB. Somedirectory contains GroupA.conf and GroupB.conf Have anyone got "include = /somedirectory/%g.conf" in smb.conf to work such that scripts in groupA.conf and groupb.conf will be executed when UserA logins? Am I using the correct syntax? If not, what is the correct syntax? I am on Debian with 3.0.10

Hi, I''m new using RoR and I have a ... trouble with f.collection.select What I have in a table is ... for example group code GroupA 07A GroupA 08A GroupA 10B GroupB 06A GroupB 11B GroupB 07B GroupC 10A GroupC 09A GroupC 09B when I use <%= f.collection_select :grupo, Equipo.find(:all), :id, :name, prompt: ''Choose a Group'' %>

I have two networks connected via ipsec with openswan. Each network contains one samba server managing one workgroup each one. The network structure is the following one: Network 131.0.0.0/16--Samba: 131.0.0.106 (workgroup groupa) --- 200.x.x.x ----internet----- 64.x.x.x ---- Samba: 192.168.1.1 (workgroup groupb)--Network 192.168.1.0/24 Machines in groupa (network 131.0.0.0/16): pc3 (131.0.0.2,

Hi, sorry if this has been asked before, but I just can't find anywhere on the net that tells me how to do this. I've been trying for ages to get this right, using various forms of --include-from, --exclude, --filter, etc. I want to copy only specific directories that contain specific filetypes, from sourcedir to destdir. For example, I want to copy all .mp3 and all .ogg files found in

Dear list, I am having some problems with extracting Variance Components from a random-effects model: I am running a simple random-effects model using lme: model<-lme(y~1,random=~1|groupA/groupB) which returns the output for the StdDev of the Random effects, and model AIC etc as expected. Until yesterday I was using R v. 2.0, and had no problem in calling the variance components of the

Hello All, i am repeating this question for the sixth time but i think i was not explaining the problem correctly. ............. Now i will try to explain it...... I have 4 telephone lines(PSTN) in my PBX. Now I want to make groups of the extensions to use that lines. e.g. extensions 12,13 & 31 are in groupA extensions 14 - 20 are in groupB extensions 21 - 30

Hi all! Here's the problem we have since patching Monday night. Tuesday morning Samba wasn't running, but started fine, and everything seemed to be working. Were currently running samba3.0.24-2.23 and I believe before the patch we were running samba3.0.22-13.30. We have some samba shares where we have subgroups that only a select group of people of the parent group are allowed to

Hi, I'm looking for an easy way to discretize factors in R I've noticed that the lm function does this automatically with a nice result. If I have group <- c("A", "B","B","C","C","C") and run: lm(result ~ x1 + group) The lm function has split the group into separate binary variables {0,1} before performing the

When I build an smb.conf using a line like: include = /usr/local/samba/lib/%G.conf then it works beautifully for the shares that are listed in the appropriate <primary group>.conf files, that is, I can connect to them and all... However, I can only _browse_ the shares listed in the main smb.conf file, not the ones in the <primary group>.conf files that should be included, even

Hello there, I would like to produce a plot of x<-c(4,5,6),which is the mean of each group and y<-c('groupA','groupB','groupC'). plot (x,y) can not produce any graphics because y is not numerical. What should I do to produce this graphic? Thank you in advance Lisa Wang Princess Margaret Hospital Toronto,Ca

Dear All I have a question from you, if you can please answer it. I have a linux server, with samba installed on it. I have 3 groups as, GroupA, GroupB, GroupC Each group is having let suppose 10 members from 0-9 I have 3 shares on my smb.con as Share1, Share2, and Share3 Now what I want it to give the read access to every one on each share and give write access of GroupA to Share1, Share2 give

Hello R help members. I came across today with an article on Barnard's exact test (http://www.cytel.com/Papers/twobinomials.pdf), that is supposed to give a more powerful fisher.test - Because it doesn't assume that we know the row and column totals are in advance. Any pointers to such a function ? Thanks, Tal -- ---------------------------------------------- My contact information:

i have 2 groups i want to compare: group A and group B each group contains let's say 20 patients i want to perform a Fisher Exact test on genotype distribution so, see if there is a sign diff in genotpe frequency/distribution (#AA, #AB, #BB) between group A and B not for 1, but for 1000 different genes my question: how should i build my table so i can do: test <-

Hi All, My apologies if this is a totally newbie question. I want to calculate the probability that a particular set of genes is picked repeatedly for 3 samplings. For example, if from a total of 'N' genes, I pick 'A' number of genes in the first pick, 'B' number of genes in the second pick, and 'C' number of genes in the third pick, I would want to calculate
