Sampling problem
Hey, I am hoping someone can help me with a sampling question. I have a data frame of 8 variables (the first column is the subjects' id): SubID CSE1 CSE2 CSE3 CSE4 WSE1 WSE2 WSE3 WSE4 1 6 5 6 2 6 2 2 4 2 6 4 7 2 6 6 2 3 3 5 5 5 5 5 5

Computing Rolling Average
Hi, Can anyone suggest a clever way to compute a rolling weekly average of the columns in a matrix? The column bit is straightforward – use apply given a function which does what you want on a column. With regard to a particular column, the obvious way is to run a for loop indexing the last 7 days and computing the average . I simply would like to know if there is a better / quicker way.

Hi, You may try: dat1 <- structure(list(SubID = 1:8, CSE1 = c(6L, 6L, 5L, 5L, 5L, 5L, 3L, 3L), CSE2 = c(5L, 4L, 5L, 4L, 6L, 4L, 6L, 6L), CSE3 = c(6L, 7L, 5L, 3L, 7L, 3L, 6L, 6L), CSE4 = c(2L, 2L, 5L, 4L, 5L, 6L, 3L, 3L), WSE1 = c(6L, 6L, 5L, 4L, 6L, 4L, 6L, 6L), WSE2 = c(2L, 6L, 5L, 4L, 4L, 3L, 5L, 5L), WSE3 = c(2L, 2L, 4L, 5L, 4L, 7L, 2L, 4L), WSE4 = c(4L, 3L, 5L, 2L, 1L, 3L, 1L, 7L)),

How to secure web services created by ActionWebService?
Hi, Does anyone know how I can go about securing web services created from ActionWebService?

function for linear regression with White std. errors
I would like to know if there is a function that will run a linear regression and report the White (heteroscedasticity consistent) std. errors. I've found the hccm() function in the car library, but that just gives me the White covariance matrix. I'd like to be able to see the White std. errors without having to do much more work, if possible. Thanks, Brian

mkstemp permission denied
We are using rsync to push DNS records from one machine (running rsync 2.5.6 as a client process on Debian woody) to a collocation server ( running rsync 2.5.6 as a daemon on RedHat 7.3). To test this process we are using a script that pushes one file from the Debian box to the collocation server. It appears that a file transfers, but upon checking there is no file transfer and an error in the

ANN: WSS4R was released
Hi everyone, I released WSS4R: http://www.rubyforge.org/projects/wss4r. WSS4R is a subset of a web service security standards implementation. It''s based on soap4r and tested with Microsoft .NET WSE 2.0 and Sun Java JWSDP 2.0. WSS4R supports username authentication, signing and encryption. It also has limited support for actionwebservice / rails. Currently, there is no documentation,

Read from url requiring authentication?
Hi all, I'm looking into opening an url on a server which requires authentication. After failing to find some kind of connection structure to fill in I turned to explicitly stating the credentials in the url itself (e.g. "http://username:pass at site.com"). Sadly this didn't do the trick either and both source() and url() failed trying to resolve the username () Is there

plot function creating bars instead of lines
Hello, I am having a problem where code that plots lines using a different data frame plots bars with the current data frame (I am intended to plot lines). The code specifies lines (see below), so I can't figure out why the results are bars. I suspect that it may have something to do with the fact that in the data frame where the code worked as intended, the both variables specifying

deriving mean from specific cases
Hi all, I have a large dataset that has >10k entries. The dataset is stored in a dataframe with the headers: SubID Condition1 Condition2 Result1 Result2 There are multiple entries for a given SubID(Subject ID). Condition 1 has 3 levels and condition2 has 2 levels (therefore there are 6 possible combinations all together e.g. Cond1 Level1 x Cond2 Level 1 etc.) and i need to compute for 1. The

Problem to remove loops in a routine
Dear R-users, I have written the following code to generate some trellis plots. It works perfectly fine except that it is quite slow when it is apply to my typical datasets (over several thousands of lines). I believe the problem comes from the loops I am using to subset my data.frame. I read in the archives that the tapply function is often more efficient than a loop in R. Unfortunately ,
