similar to: Error in memory.size(size) when calling R in batch mode (but not in interactive mode)

I am currently running an R program on a computer with 16 Gb memory (Windows7, 64 bit). When I look at the task manager, I see that only 4 out of the 8 CPUs are being used. Is this due to some missing in the R code, or should I change something to the settings of the computer?

Dear all I am trying to build a package, and get the error message: ""packaging into .tar.gz failed"". I have also installed the same package directly from a locally created zip file. In this case, the package is put correctly under C:\R\R-2.15.0\library. However, when I check the package, I get another error message, stating "ERROR: compilation failed for package".

Dear all I have written a function in C++ , equil_distC, that I am calling from an R script. In the last few days, R has repeatedly crashed when calling this function, or delivered obviously wrong outputs. However, when I restarted R after the crash, the results turned out to be OK most of the time although I had not modified the C++ code. Although the code runs correctly now, I am not sure

Dear all, I am encountering problems with the application of ddply within the body of a self-defined function. The script is the following: moncostcarmoto <- function(costtype){ costaux_result <- data.frame() for (purp in PURPcount){for (per in PERcount){ costcarin =

Dear all I have written a function, "calibrateCES", in which a function is called, "BPGC", which was written in the enclosure of "calibrateCES". Until the most recent version of my program, "calibrateCES" always used "BPGC" as planned. Following a modification which does not affect "BPGC" directly (although it does affect one of the

Dear all, I have problems loading a library in the 64 version of R. The following happens: · I have a file, equildistC.cpp, which contains a few lines of C++ code. · I have compiled the file using the following commands: PATH =

dear all, This is a probably a silly question. If I type > grep("x",c("a.x" ,"b.x","a.xx"),value=TRUE) [1] "a.x" "b.x" "a.xx" Instead, I would like to obtain only "a.x" "b.x" How is it possible to get this result with grep()? many thanks for your attention, best, vito --

Hello CFS, I was wondering if the new SLES10 kernel will be part of the 1.6.4 release. It appears to be tracked by: https://bugzilla.lustre.org/show_bug.cgi?id=13874 As this contains a major security fix (privilege escalation), it is a mandatory upgrade in many places and it would be nice to not have to roll our own kernel. Thanks, Kit

dear all, Is the following intentional? Am I missing anything in documentation? d<-data.frame(y=rnorm(10,5,.5),exp=rnorm(10), age=rnorm(10)) formula(lm(exp(y)~exp+age, data=d)) #--> exp(y) ~ exp + age formula(lm(exp(y)~., data=d)) #--> exp(y) ~ age variable 'exp' (maybe indicating "experience") is not included in the model. The same happens with 'log' (and

Functions are first class objects, so some kind of collision is bound to happen if you do this... so don't. -- Sent from my phone. Please excuse my brevity.

Hi, Im using roaming profiles on a FreeBSD 4.7 server for all the Win2K clients on the network. At this moment only 1 client is working on the domain. The roaming profiles are working OK, but it takes such a long time (2 or 3 minutes) to login or to logout. The server is quick enough (dual processor 1Ghz, 512 MB memory, 230 GB harddisk), but why does this take so much time? It's very

dear all, When I use all.vars(), I am interest in extracting only the variable names.. Here a simple example all.vars(as.formula(y~poly(x,k)+z)) returns [1] "y" "x" "k" "z" and I would like to obtain "y" "x" "z" Where is the trick? many thanks vito -- ==================================== Vito M.R.

Dear UseRs, maybe is a silly question: how can I get Empirical CDF values from an object created with ecdf()?? Using print I obtain: Empirical CDF Call: ecdf(t) x[1:57] = 4.1, 4.4, 4.5, ..., 491.3, 671.27 Thanks in advance.

dear all, I am stuck on the following problem. Give a string like ss1<- "z:f(5, a=3, b=4, c='1:4', d=2)" or ss2<- "f(5, a=3, b=4, c=\"1:4\", d=2)*z" I would like to remove all entries within parentheses.. Namely, I aim to obtain respectively "z:f()" or "f()*z" I played with sub() and gsub() but without success.. Thank you very

Well... ?terms.formula says: "data: a data frame from which the meaning of the special symbol . can be inferred. It is unused if there is no . in the formula." So this seems to me to be an obscure bug, as I have found no warning against this admittedly confusing but still, I think, legal syntax. Note: > d <- data.frame(log = runif(10), x = 1:10) > y <- rnorm(10,5) >

Dear all, It appears that MASS::polr() and Design::lrm() return the same point estimates but different st.errs when fitting proportional odds models, grade<-c(4,4,2,4,3,2,3,1,3,3,2,2,3,3,2,4,2,4,5,2,1,4,1,2,5,3,4,2,2,1) score<-c(525,533,545,582,581,576,572,609,559,543,576,525,574,582,574,471,595, 557,557,584,599,517,649,584,463,591,488,563,553,549) library(MASS) library(Design)

Dear all, I would like to write a function like: myfun<-function(x,fn) {xx<-exp(x); x*fn(xx)} where fn is a symbolic description of any function with its argument to be specified. Therefore myfun(5,"2+0.3*y^2") should return 5*(2+0.3*exp(5)^2), myfun(5,"log(y)") should return 5*log(exp(5)) and so on. I tried with "expression" and others, but without success.

Dear all, I have the following (rather) strange problem.. For some reasons, I finally work with a variable whose name includes an R function, "a.log(z)", say. And that is a problem when I call it in a formula, for instance: > myname<-"a.log(z)" > dd<-data.frame("a.log(z)"=1:10,y=rnorm(10)) > o<-lm(y~1,data=dd) >
