Hi, I am fairly new to R and still trying to figure out how it all works, and I have run into a few issues. I apologize in advance if my questions are a bit basic, I'm also no statistics wizard, so part of my problem my be a more fundamental lack of knowledge in the field. I have a dataset that looks something like this: Week Subj Group Readout 0 1 A 352.2 1 1 A

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'' %>

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, 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

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 find some troubles about how to extact the row from csv. file by using if-statement condition. I want to extract the row if the rainfall is greater than the mean of rainfall and using the wrfta divided into 3 groups that's rainfall greater than mean -> group A ( create file group A_rain) -> groupB ( create file group B_rain)

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

So I discovered yesterday that if puppet changes the gid of a group it doesn''t go through the file system and update them with the new correct gid (at least this was the case on RHEL5 and client puppet v2.6.16 and puppetmaster 2.7.12). Now I thought that it might be possible to have puppet execute something like find /home/ -group <old_gid> | xargs chgrp groupname. However

I making an xyplot and the y label is too long and needs to be in two rows, but when I brake it there is a huge gap between the last text string and the expression, and I can't get rid of it. Any ideas? Data: structure(list(Temp = c(8L, 8L, 8L, 8L, 8L, 8L, 12L, 12L, 12L, 12L, 12L, 12L), CO2 = c(380L, 380L, 380L, 750L, 750L, 750L, 380L, 380L, 380L, 750L, 750L, 750L), Treat = structure(c(3L,

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, 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

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 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

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

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

I am using lme from the nlme package to fit a mixed model. We have observations nested in patients(encounters) and patients nested in groups (2 different treatments). We are interested in the differences between the 2 groups, both the means and the standard deviations (are patients in group A less variable than those in group B? both within patient and between patient within group). Here is

Hi I have to use find to change the perms of a directory and files within that directory recursively but i need to exclude a directory within the top level directory, as its a netapp and so contains a read only .snapshot dir. I have tried... # find /var/data/foo -path '\.\/\.snapshot' -prune -o -exec chown usera:groupb {} \; but chown: changing ownership of

Hello All !!! I have 4 PSTN lines in the PBX server 1,2,3,4. First line will be used by only one extension (i.e. for the boss) for incoming and outgoing. This line is dedicated for him only.( The remaining lines will be shared by the employees 1) Group A have access to lines 2 , 3 & 4. 2) Group B have access to lines 3 & 4 3) Group C have access to line 4

Hi everyone, I am fairly new to R, and I am aware that others have had this problem before, but I have failed to solve the problem from previous replies I found in the archives. As this is such a standard procedure in psychological science, there must be an elegant solution to this...I think. I would much appreciate a solution that even I could understand... ;-) Now, I want to calculate a

Dear professors and collegues I need to perform a analysis of dates from a nested experimental design.
