hi R folks, I need read a file from hardisk or www web. Then I need to define some new functions according to the contents of the read file. For example, i need write a package name "mypackage" like this: >library(mypackage) >read(some_file_on_web) #to see its content, suppose it contains: eat.drink.sleep then 3 new functions need to be created and usable. the problem is, how

Hi All, I've been having a little trouble using R2HTML and a loop, but can't figure out where the problem lies, any hints gratefully received. My code at the minute, (Which does work) is in the following: library(R2HTML) HTMLStart(outdir = file.path("C://Example_work","R_projects","Dynamic_creative"),filename = "RMDC_mockup",Title="Mock up for

I keep expecting R to have something analogous to the =count function in Excel, but I can't find anything. I simply want to count the data for a given category. I've been using the ddply() function in the plyr package to summarize means and st dev of my data, with this code: ddply(NZ_Conifers,.(ElevCat, DataSource, SizeClass), summarise, avgDensity=mean(Density),

Hello, I'm not a Stata user so I'm trying to reproduce Stata results that are given to me in R. I would like to use a GLM with a complementary log-log function. The stata code I have is: glm c IndA fia, family(binomial s) link(cloglog) offset(offset) The R code is: glmt <- glm(data=dataset, c ~ IndA + fia, offset = offset, family = binomial(link = cloglog)) Which yields

Hi there, I am looking to install R on Mandriva-linux. But on the UK mirror site I found only Debian, Redhat, Suse, and Ubuntu, but not Mandriva. Any help would be greatly appreciated Thanks -- ------------------------------------ Abdel Hannachi Reading, UK

Are there any R rpm's for Mandriva 2008.1? I found a couple of dodgy ones that wouldn't install so far (rpmfind.net). (Sorry that seems so far the only Linux distribution that recognizes my hardware on my new laptop correctly. I'm more familiar to Fedora and Suse so perhaps I'm just doing something wrong?) Joanne

Hi expeRts, I would like to calculate weighted mean by two factors. My code is as follows: R> tmp <- by(re$meta.sales.lkm[, c("pc", "sales")], re$meta.sales.lkm[, c("size", "yr")], function(x) weighted.mean(x[,1], x[,2])) The result is as follows: R> tmp size: micro yr: 1994 [1] 1.090

Dear all, A very basic terrain calculated as a matrix from Spatial Points Patterns: #interpolate using the akima package library(akima) terrain=interp(ppoints$x,ppoints$y,ppoints$marks,xo=x0,yo=y0, linear=F) > class(terrain) [1] "list" > class(terrain$x) #these are the x-coord i.e: [1...1000] [1] "numeric" > class(terrain$y)#these are the y-coord i.e: [1...1000] [1]

Hello List, I saw the example in "Writing R Extensions" where a convolve function is implemented in C, which is makes the whole business of calling C from R easy to understand. Is there a similar example of how to call Fortran 90 from R somewhere? Thanks, Max

I just uploaded an initial RQuantLib package to R's site in Vienna. RQuantLib is an R [ http://www.r-project.org ] package to access the powerful QuantLib [ http://quantlib.org ] libraries for quantitative finance. RQuantLib is at an early stage: I only defined two basic classes Option and ImpliedVolatility with print and summary methods, and European and American options on top of them.

I've been hacking at the JitterBug sources a little, so that it should work better with mailing lists. It has been running with the core team list for a while and seems to be OK. I will now move the forwarding address to the r-devel list where it really belongs. I hope this will make it easier for people outside the core team to contribute to the development of R by participating in the

Hi All, I've done some work recently making some of our image analysis library callable from R and Splus. Most of the C image functions use an abstract data type, and R only sees a pointer to this. All memory allocation is done by the library. This leads to some interesting problems. I'm interested in your views about possible solutions. 1) assignment. something like a<-b, where a and

Hi, I have two t100p cards installed. One card connected to the PSTN, the other card is hooked to the Definity PBX with a T1 cross over cable. The card connected to the PSTN works fine. The problem is with the card hooked up to the PBX. The light behind the card is green, but when I dial from this card I get an error. Its says it could start the D-Channel. Could someone help me out with this

Greetings, Does anyone know if there is a cost effective way to interface an older AT&T Spirit system into Asterisk. I'm only interested in A) being able to offer voicemail and B) possibly an AAT to callers. I've thought about just stringing the FXO cards into the line1/2 slots that go into the Spirit system... asterisk would pickup if no one answered the Spirit phones.... however....

Hi, We are currently in the process of installing an Asterisk box between our legacy PBX (NEC Xen Master) and the Telco (Telstra). Originally the PBX was connected to the telco via 8x BRIs. Our new Asterisk box has been setup with 2 OpenVox B800P cards. Each card has the 4 ports in TE mode and 4 ports in NT mode. The NEC PBX is connected to the Asterisk boxes NT ports and the Asterisk box is
