Sorry, if this question is rather basic, but being a newbie I still have problems to think in the "R way". My problem is as follows: - I have a data frame X with stock prices X$Price and corresponding dates X$Date. - Now I want to get for each date x in X$Date the index z, such that z = min (a | X$Date(a)>x and X$Price(a)>Price(x) To put it simple, I am looking for the

Dear list members, we are running samba 2.2.3a-6 with debian woody. Printing from win98, NT4.0 AND two win2k PC works, but with two other win2k PCs printing is not possible: The following german error Message is displayed in the win2k printer configuration: "Zugriff verweigert; kein Verbindung m?glich" The english translation could be something like this: "access denied; no

Hi, My name is Tom Faulhaber. I am the network administrator at a small company in Providence,RI. I am running Samba 2.2.2 on a Redhat 6.1 machine on a Novell 4.21 network. The workstations are Win98SE. The Linux box is being used for the company intranet (Apache 1.3.22). Everything runs fine, however I am completely stumped on one issue (so far). That issue is: network connectivity. If I

Hi all I am beginning in asterisk and am making tests with an ata-186. For the time being the tests are going well, however have a doubt. I am thinking about using a canal e1 with plate digium. Assuming that the company of telecommunications supplies e1 with 30 canals and numeration to me 4000-0001 4000-0029. she is possible to configure asterisk in way that somebody of is dials 4000-0025, to

Hi all, as I am trying to move slowly from just "working" to "good" code, I'd like to ask if there's a smarter way than using a for-loop in tasks like the example below. I need to obtain the extrema of the cumulated sum of a detrended time series. The following code is currently used, please have a look at the comments for my questions and remarks: system.time({ X

Greetings, I am interested in using a generalized linear mixed model with data that best fits a beta distribution (i.e., the data is bounded between 0 and 1 but is not binomial). I noticed that the beta distribution is not listed as an option in the "family objects" for glmmPQL or lmer. I found a thread on this listserve from 2006 ("[R] lmer and a response that is a

Hi all, I would like to estimate power and necessary sample size for a GLM with a response variable that has a poisson distribution. Do you have any suggestions for how I can do this in R?

Craig, Thanks for your follow-up note on using the asypow package. My problem was not only constructing the "constraints" vector but, for my particular situation (Poisson regression, two groups, sample sizes of (1081,3180), I get very different results using asypow package compared to my other (home grown) approaches. library(asypow) pois.mean<-c(0.0065,0.0003) info.pois <-

Hello Everyone! It has been my pleasure and privilege to serve as the FreeBSD Security Officer for the past 3+ years. With the crucial support of the FreeBSD Security Team members, a lot has been accomplished: hundreds of security issues have been researched and tracked, with some resulting in security advisories and patches; software in the Ports Collection are updated more quickly

Hi all, in order to verify some results I did the following test in R (2.4.1., windows system): X <- cumsum(rnorm(1000000)) for (i in 1:1000) { tmp <- seq(1,length(X),by=i) X.coarse <- X[tmp] X.return <- diff(X.coarse) X.scale.mean[i] <- mean(X.return) } plot(X.scale.mean,type="l") As X is a random walk with

Hi. Can anyone suggest a simple way to obtain in R a list of vector coordinates of the following form? The code below is Mathematica. In[5]:= Flatten[Table[{i,j,k},{i,3},{j,4},{k,5}], 2] Out[5]= {{1,1,1},{1,1,2},{1,1,3},{1,1,4},{1,1,5},{1,2,1},{1,2,2},{1,2,3},{1 ,2,4},{1,2, 5},{1,3,1},{1,3,2},{1,3,3},{1,3,4},{1,3,5},{1,4,1},{1,4,2},{1,4,3}, {1,4,

Well i haven't seen anyone talk about this, so i was just wondering if FreeBSD is affected by this. http://xforce.iss.net/xforce/xfdb/6508

Hallo, I am a newbie to R and desperatley seeking some material about fractal geometry. I found the great library on wavelet analysis of images and I'm now also keen on finding a similar package for calculating fractal parameters for given images. Does anybody know something about such a package? Every hint is greatly appreciated!! I searched already the database, but did not find anything

I'm looking to add a single FXO port to my Asterisk box. It looks like my options are a Digium Wildcard X100P off eBay for $6.99, or a Wildcard TDM400P with an FXO Module from Digium for $125. Can anyone explain the tradeoffs (other than the ability to put 4 FXO/FSO modules on the TDM400P). What about RTC for the system - I know the TDM400P provides it. Does the X100P? Thanks!

Dear sirs, 1...........Kindly tell me is it possible to form a matrix which contains a no of matrices.. for eg.. if a,b,c,d are matrices.... and e is a matrix which contains a,b,c,d as rows and columns.. 2..........Is it possible to form array of array of arrays for eg.. "A" contains two set of arrays (1,2)...and each A[1] and A[2] individually contains two set of arrays I tried like

As of R 1.7.0, princomp no longer accept matrices with more coloumns than rows. I'm curious: Why was this decision made? I work a lot with data where more coloumns than rows is more of a rule than an exception (for instance spectroscopic data). To me, princomp have two advantages above prcomp: 1) It has a predict method, and 2) it has a biplot method. A biplot method shouldn't be too

Dear Sir / Madam, I am new for R coding. Kindly help me out in sorting out the following problem. There are 50 rows with six coloumns(you could see in the attached .txt file). I wish to go for filtering this 50 rows for any one of the six coloumns satisfying the value >= 64. I need to have a final table with rows having >= 64 value in any one of the six coloumns and the rest could be
