similar to: how to assign a group mean to individual cases?

I used the following to assign each row the group average, where w is the new group average variable, x is the variabale to be averaged, and g is the nominal group indicator: w <- ave(x,g) Now I want to calculate the group average, but WITHOUT each row's value of x. Is there an easy way to do this? I'm sure I'm missing something obvious here, but for the life of me I can't

I'm sure this is easy, but I'm having a hard time figuring out how to recode some data in R. I have a variable "numpeers" which is valued 1, 2, or 3. I also have three other variables called "w9zd9_1," "w9zd9_2," and "w9zd9_3." I want to use these variables to create a new item called "distot." Specifically, here is what I want to do:

All, I've coded a function and it works manually if I copy it line by line into R. However, when I try to "load" (copy and paste) the entire function into R, I get the following error after the listed line of code: + N.j.list = lapply(rej.hyp, length) Error: symbol print-name too long Does anyone you know what this error means? Strangely, when I copy the same line verbatim

All, I have a repeated measures data frame and was wondering if the covariance matrix can be calculated via some created indexing or built-in R function. Specifically, say there are 3 variables, where potassium concentration is measured 6 times on each patient. Patient number (discrete) Time (1 to 6, discrete) Potassium (continuous variable) I want the covariance/correlation matrix for the

Dear R list, I have a sequence of weekly observations of number of adults and larvae in various size classes from a butterfly population living in a subtropical area with pronounced wet and dry seasons. Wet and dry seasons are each defined 26 weeks long with fixed start and end dates. The data span 103 weeks (two seasons each of wet and dry) with some missing weeks. What I would like to do is

Dear R Help, I've just installed 1.7.1 and have found that the console now exhibits odd behavior when I paste commands into it. I'm on a PC running Windows XP Professional. I use Word as my script editor, and then paste commands into the R console using the standard Windows "copy" within Word then "paste" within Rgui. This worked without a hitch in 1.7.0, but now in

All, I'm trying to create an augPred plot in the nlme library, similar to the plot on p.43 of Pinheiro & Bates (Mixed Effects Models in S and S-Plus) for their Pixel data. My data structure is the same as the example but I still get the error msg below. > comp.adj.UKV <- groupedData(adj.UKV ~ Time | Patient_no/Lisinopril, data = comp.adj.UKV.frm, order.groups = F) >

So, I've finally gotten around to installing a Samba4 AD DC. I've joined a Win7 and Ubuntu machine to the domain so far, and all works perfectly. Great job guys, it's nice to see this functionality working solidly on Samba! The problem is coming in on the actual DC host. My Ubuntu laptop is running winbindd 3.6.18, and as I said, all went flawlessly. The DC host is running

Hi Team, We have a weird issue that we are trying to understand. We have winbind set up and working successfully for user authentication with passwords via ssh. We have pam.d/system-auth-ac and password-auth-ac (symlinked) set to require membership of a group which works great via password authentication. However, if the user has a ssh key set up, they seem to bypass the group membership

I have a really long functions, and at the end of the function, I am using a if statement to tag certain keywords based on whether they have certain values contained in them. However, the if statement doesn't seem to work. When I had split up the commands into various functions, it worked fine, but I'm not sure what going on now that it's combined into a single function. myfunc

I'm doing in-site migration of accounts from /etc/passwd to an LDAP directory. The migration should be progressive (not all users at the same time). I'm already able to check mail for accounts in /etc/passwd and accounts in LDAP. The problem is with mail delivery. I'm using Postfix + Dovecot-LDA. This is the error I get with every delivery -- dovecot: Oct 03 00:16:09 Info:

How can I print a data.frame to a PDF with pdf()...dev.off() ____________ Paulo E. Cardoso [[alternative HTML version deleted]]

I'd greatly appreciate your help in making a bar graph with multiple variables plotted on it. All the help sites I've seen so far only plot 1 variable on the y-axis Data set: I have 6 sites, each measured 5 times over the past year. During each sampling time, I counted the occurrences of different benthic components (coral, dead coral, sand, etc.) over 5 transects in each site site
