similar to: group mean, minus each row's value

I need advice on how to create a variable that is the group mean of another variable. For example, I have a variable called x for which each row in the data set has a value. I also have a nominal variable called g that indicates which of 100 different groups each row belongs to. So, I want to create a new variable called w, which is the group mean of x for which ever group the row belongs to (as

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) >

Hello List does anyone have an R function for the Lambert W function? I need complex arguments.

Hi! I searched some time ago a way to get the Wilcoxon test results as a table more or less formatted. Nobody told me any solution and I found nothing on the Internet. Recently I came across this link ( http://myowelt.blogspot.com/2008/04/beautiful-correlation-tables-in-r.html), which helped me to find a solution. Here's the solution (I'm using R Commander): W <-

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

Hi All. I have R code whose functionality is being replicated within a C+ program. The outputs are to be compared to validate the conversion somewhat - however (as is always the case) I have stuffed my code with random number calls. Random uniform numbers in C+ are being produced using the (Boost) mersenne-twister generators (mt11213b & mt19937) - which is the default type of generator

Dear R list, What's the best way in R to fill a matrix who's entries depend on some function of the indices? I'm currently doing: Q <- matrix(0, k, k) for (A in 1:k) { for (B in 1:k) { Q[A,B] <- my.function(A,B) } } but I wonder if there is a more terse way.

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 thinking of using Samba to allow my laptop 486 to access the CDrom, internet link and large hard disks in my Amiga. Does anyone know if this would be easy to do, and if it's possible to get Samba running using Miami? cheers, Evan.

Did the logs provide any hints as to what the issue may be? Diego On Sat, Jun 3, 2017 at 12:16 PM, Diego Remolina <dijuremo at gmail.com> wrote: > Thanks for taking the time to look into this.

I would like to know how to calculate the amount of bandwith I would need to host X number of calls. For example, if user A in San Francisco with an ATA 186 calls user B in New York with an ATA 186 and Asterisk is being hosted in a PC in Miami. How much bandwith do I need to have in Miami? Do I just need bandwith for the setup of the call (ie the SIP part) or are there any instances where the
