similar to: using 'sum' function in writing a function

Hi, I am writing a function that includes 'sum' function such as: f<-function(x){ c<-c(-1,0,1) f<-sum(c+x) } expecting f to be -1+x+0+x+1+x=3x. But I found out that f is sum(x). So, f is always a scalar, which means that f(c(0,1)) is not a vector as c(0,3), but 3(0+1)=3. I would like to ask you helping me in solving this problem. I would like to thank you in advance. Sungsu.

Dear R users. I have data observed on the surface of a torus, and am trying to fit the nonlinear regression using the geodesic equation on a torus. Could anyone give me a helpful advise on this problem? I would definitely appreicate your reply. Sincerely, SUNGSU KIM [[alternative HTML version deleted]]

I want to predict values from an existing lm (linear model, e.g. lm.obj) result in R using a new set of predictor variables (e.g. newdata). However, it seems that because my linear models was made by calling scale() on the target predictor that predict exits with an error, "Error in scale(xxA, center = 9.7846094491829, scale = 0.959413568556403) : object 'xxA' not found".

The interpretation of regular expressions with repetition quantifiers in the 'gregexpr' function seems to have changed between R Version 2.2.0 and 2.3.0. The 'gsub' function, however, gives the same results in R Versions 2.2.0 and 2.3.0. Below is an example that demonstrates the version differences of the 'gregexpr' function. I am not sure whether this new behavior is

I have a question regarding accessing the names of list components when applying a function with lapply. Here is an example that demonstrates what I'd like to do. I have a list like this one: mylist <- list(a=letters[1:10], b=letters[10:1], c=letters[1:3]) Now I would like to append the names of the list components to their corresponding vectors with the c() function. I thought this

Dear R Help, I believe the glmer() function in lme4 automatically fits an unstrucruted covariance matirx for the random effects. Is that true? If so, do I have an option to somehow ask for a diagonal structured covariance matrix?

Do you live in Southern California''s Inland Empire? Did you hear about the San Diego Ruby Users Group and think that''s just too far to go for me? Then you might be interested in forming the Riverside Ruby Users Group.

I''m still using CentOS 3.3 as our install mechanism, then adding some packages from a tarball of RPMs we need. Then I run # yum update yum which sometimes takes a while. Yesterday it took many hours. I like to run these from behind a firewall in our office before taking the server to the datacenter, but the delay meant a whole day''s delay in our trip to the datacenter

I'm trying to connect a sip call from sipgate to Asterisk A to Asterisk B. Both are behind NAT, but port forwarded. I get the connection, but no voice - either in or out. I can call on SIP from A to B (and from B to A). Do it all the time. Asterisk A receives SIP calls from Junction and Teliax. CLI on A looks right: == Using SIP RTP TOS bits 184 == Using SIP RTP CoS mark 5 ==

I wrote some code which reads a gzipped text file directly from the web with gzcon(url()) and it works perfectly on OSX, but I cannot get it to work on linux at all, trying several different R versions and linux distributions. Any ideas? Here's an example of my code: z <- gzcon(url("ftp://ftp-private.ncbi.nlm.nih.gov/pubchem/.fetch/8897497837079742771.sdf.gz")) sdf <-

Dear R People: Here is a really goofy question. I have some objects which have 2 classes: data.frame and ucr. Also, the classes will always be in that order. I have tried all sorts of things, but to no avail. listucrModels <- function(envir=.GlobalEnv, ...) { objects <- ls(envir=envir, ...) if (length(objects) == 0) NULL else objects[sapply(objects, function(.x)

Dear R users. I have written my R code. It runs in the version 2.3.1, but not in the version 2.5.1. The error message is shown below. Error in .Fortran("DEPTH", u, v, as.integer(size), as.single(x), as.single(y), : Fortran symbol name "depth" not in load table Could any one advise me what I could do to run my code in 2.5.1? Sincerely,

I'd like to know how to obtain a table of anova of a 3^2 desing with linear and cuadratic sum of squares because if I use "aov", this comand only bring me the linear sum of squares: > A<-rep(c(rep(-1,3),rep(0,3),rep(1,3)),2) > B<-rep(rep(c(-1,0,1),3),2) > y<-c(1.5,1.4,0.8,3.5,2.9,1.8,4,3.8,2.7,1.2,1.3,1.2,3.2,2.5,2,4.2,3.4,3 ) >

All, In the function below I have 24 individuals and 6 calculations per individual. The 6 calculations are collected each time in a 1:24 loop when calculating "delta". I'd like to collect all 144 = 24*6 calculations in one vector ("delta.patient.comb"). The function works as is via indexing, but is there an easier way to collect the measurements via appendinng the 6

Dear list, I am running into 2 problems when using the optimize function from the stats package (note: I've also tried unsuccessfully to use optim, nlm, & nlminb). The second problem is caused by my solution to the first, so I am asking if anyone has a better solution to the first question, or if there exists a solution to the second problem. I should also mention that what I am
