Hi Apologies in advance if I've missed something obvious. I have read the Sweave manual, the first article in R News, looked at the Help pages, googled Sweave and words like loop, output, files, multiple, done much the same on R site search (in case I missed something on Google) and I couldn't find exactly what I'm after. What I'm trying to do ?---------------------- Make

Hi all, I have (yet another) question about a function in R. What I would like to do is test for the presence of a certain value in a vector, and have the positions that this value is at returned to me. For example, let's say I have a vector: x <- c(1,1,2,2,3,3,4,4) Now I would like a function that would return positions 3 and 4 should I test for the value "2". Or 5 and 6

I keep finding myself in a situation where I want to calculate a variable name and then use it on the left hand side of an assignment. For example iteration <- 1 varName <- paste("run",iteration,sep="") myList$parse(text=varName) <- aColumn I want to take some existing variable "aColumn" and use the name "varName" name for it and put it into a

Dear list: I am trying to calculate the intersection area between two irregular polygons (see example data below). set.seed(1234) theta <- seq(0, 2 * pi, length=(100)) poly1<- cbind(c(0 + 1 * cos(theta) + rnorm(100, sd=0.1)), c(0 + 2 * sin(theta))) poly2<- cbind(c(0 + 2 * cos(theta) ), c(-1 + 1.5 * sin(theta)+ rnorm(100, sd=0.1))) plot(x, y, type = "n", ,

Hello, I need to capture calee's audio in real-time in order to capture operator messages (I've written sound recognition software that works with Jack: http://github.com/Motiejus/SoundPatty/). Jack does the following: Incoming call audio -> audio in to jack, audio out from jack -> current Asterisk application Outgoing call audio <- current Asterisk application However, I need

dear R experts--- t <- 1:30 f <- function(t) { cat("f for", t, "\n"); return(2*t) } g <- function(t) { cat("g for", t, "\n"); return(3*t) } s <- ifelse( t%%2==0, g(t), f(t)) shows that the ifelse function actually evaluates both f() and g() for all values first, and presumably then just picks left or right results based on t%%2.

Hi, I tried many things to insert a data in an Oracle Table, but the Rails compiler never Works! I create this Oracle table: CREATE TABLE "FOO" ( "id" int NOT NULL primary key, "acolumn" VARCHAR(10) NULL ) and when i tried to insert a new row the Rails compiler tell me : OCIError: ORA-00904: invalid column name: INSERT INTO AGO.FOO (acolumn, id)

To make a new istance of an Oracle table with Rails, i need that this table had a column named ''id''. This ''id'' must be Primary Key & auto_increment;. How Can I modify the ''id'' properties to do it Auto_increment in Oracle? -- Posted via http://www.ruby-forum.com/.

Hi R sages, Here is my latest problem.

Hello again R users, I have a devilishly hard problem, which should be very simple. I hope someone out there will have the answer to this on the tip of their tongue. Please consider the following toy example: x <- read.table(textConnection("y x1 x2 indv.1 bagels 4 6 indv.2 donuts 5 1 indv.3 donuts 1 10 indv.4 donuts 10 9 indv.5 bagels 0 2 indv.6 bagels 2 9 indv.7 bagels 8 5 indv.8

Hi all, I am looking to fit a logistic regression using the lrm function from the Design library. I am interested in this function because I would like to obtain "pseudo-R2" values (see http://tolstoy.newcastle.edu.au/R/help/02b/1011.html). Can anyone help me with the syntax? If I fit the model using the stats library, the code looks like this: model <- glm(x$trait ~ x$PC1 +

Hello all, I am trying to write a program in R in which I call a function multiple times within a loop. The problem is that sometimes the function breaks down while calling another function, and produces an error message that breaks my loop and the program stops. I would like to keep the loop running when this function breaks down, and just move on to the next iteration in the loop. Is there

I'm wondering if it's possible to use isolinux on a bootable CDR to boot an ISO9660 disk image off of the CDR's filesystem. I'm trying to make a multi-boot CD which is capable of booting both floppy images and smaller ISO9660 images (such as the debian netinst or DSL - damnsmall linux), and I am wondering if isolinux is capable of doing this (or something similar to this -

Dear List, I have a problem connecting to a CRAN mirror through a networked computer running Vista Enterprise on a Dell PC. I added http_proxy=http://gannet/ http_proxy_user=ask to the Target in the R shortcut, completed the username and password in the Proxy Authentication window, but get the following warning: Warning message: In open.connection(con, "r") : unable to resolve

Good evening all, I'm running samba 2.2.2a on RedHat 7.2 as a PDC and until today all was well. One of my users upgraded their workstation to Windows Xp pro and although they received a message "Welcome to the domain" when they try to log on they receive the message that the domain comptroller cannot be located to validate their account. The workstation show up in the browse list.

Well I thank everybody that helped me get swat working. I am very thankful. Now, though, it seems I have more problems. When I try to join my samba domain, my XP box says "a domain controller for the domain edith could not be contacted." Okay, well, after reading up on things in this list, it seems that I need to create a machine account. I didn't have to on my NT box. When I

Dear R-list, about one month back I posted here a question/idea that it would be nice to have some list of references of R in use plus some other "marketing" arguments for R to promote it. Thanks for all your responses. I was given useful responses from Armin Roehrl, Jim Lemon, Edith Hodgen, Ko-Kang Kevin Wang, Charles Berry, Martin Maechler, Spencer Graves, Paul Gilbert, Adelchi
