similar to: filling a matrix who's entries are a function of the indices?

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

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

Hello! I''ve a ubuntu server running over a HVM DomU. After a hang, the domU doesn''t start again. The domU was not able to mount the virtual machine disk so I started with a live cd and I tried to mount the disk root part / with no success so I ran fsck.ext3 and it gave me input/output error in the domU and in dom0 the kernel says: Feb 14 18:22:28 scofield last message

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

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

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:

Hi, Does anyone know if the D'agostino test is available with R ? Alex

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

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 Pengfei, Glad you tried the program and it works fine to you for the first place. Dr. Swarup and John from UIUC wrote most of the code, and released the original code to public. Dynamic slicing tool is really very useful. Giri is now far from perfect. For example, there are know bugs for multi-thread programs and I'm fixing it these weeks. I will take charge of this project for a while

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) >

Dear R users, I am looking for some advice on the proper construction of a mixed model in R, using the difference in means as the response and treating within-means residuals as a random effect. I have a dataframe (my own, a snippet of which is given below) that is composed of observations of pollen viability in flowers along tree branches. Flowers (1 to 3 per position) were collected from

It is possible at least on linux to get the port associated with a device from userspace - I'd assume that on each platform it's possible, just that libusb is incomplete (on top of being undocumented). Here's a patch for matching portnum on linux, with a few pieces pulled from libusb. It lacks autoconf macros to isolate it -- but it does appear to work. Regards, Alex Peyser On

Friends, I am having a very strange problem that I can't debug. Please help. I am using ldapsam which was working fine last night. Today without having done anything, I cannot login.
