Hello, I want to split a string including a "+" but it seems there is no effect because of this special character. Just to explain, I convert frequencies to midi notes (external program) but I don't want to keep information about quater-tone! > s <- c("Fd4+1/4") (i't a note!) > strsplit(s,"+") [[1]] [1] "F" "d" "4"

Hello, I analyse some free-sorting data so I use hierarchical clustering. I want to compare my proximity matrix with the tree representation to evalute the fitting. (stress, cophenetic correlation (pearson's correlation)...) "The cophenetic similarity of two objects a and b is defined as the similarity level at wich objects a and b become members of the same cluster during the course of

Hello, I've some problems to concatenate elements of a list: > s1 [1] 1 2 3 4 > s2 [1] 6 7 > l <- list(s1,s2) > l [[1]] [1] 1 2 3 4 [[2]] [1] 6 7 but now I want to get this: > l [[1]] [1] 1 2 3 4 [[2]] [1] 6 7 [[3]] [1] 1 2 3 4 6 7 ## l[1] with l[2] Someone can help me?

Dear all, I have a question with regard to the use of hclust. I would like to be able to specify my own distance matrix instead of asking R to compute the distance matrix for me. It is computationally easier for me this way. My question is: How can I get hclust to accept this? Thanks, Ranjan -- *************************************************************************** Ranjan

Here I got a function : f<-function(x){ res<-list() res$bool=(x>=0) res$tot=x return(res) } I want that a=res$bool and b=res$tot I know that a possible solution is : Result=f(x) a=Result$bool b=Result$tot But I don't want to use the variable Result. I'd like to write directly something like [a,b]=f(x). Is it possible ? Thank you nicolas [[alternative HTML version

I got many answers to the question I asked below , and I thank you all. Several of you told me to use ->> but told also that "it is not a recommendable way of items manipulating in R". I don't really understand what it exactly means : 1) does it mean it's not a very good way of programming , a dangerous way of programming because the variable a can be modified ? , etc Or

Hi folks, When I enabled stored configs on my puppet master, it began keeping lots of open connections to the MySQL server (as far as I understand it opened one connection for each client run and never closed them). I set up the server to close idle connections after 5 minutes. Now the database server does close the connections but the puppet master keeps them in CLOSE_WAIT state and eventually

below is a code to compute hessian matrix , which i need to generate 29 number of different matrices for example first element in x1 and x2 is use to generate let say matrix (M1) and second element in x1 and x2 give matrix (M2) upto  matrix (M29) corresponding to the total number of observations and b1 and b2 are constant.  can some one guide me or help to implement this please. I did not

Hi, I want to create a data frame similar to the following, but greatly scaled up: df <- data.frame(aaa= c("a","b","c"), integer(3), integer(3)) names(df)[2:3] <- paste("var",1:2,sep="") which yields aaa var1 var2 1 a 0 0 2 b 0 0 3 c 0 0 I would not relish having to paste 'integer(3)' 5000 times :(

Hi. I have repeated measures data of the form where each observation is a trial, and trials are grouped by subject, and variables encode whatever level of a factor was present during that trial, and the dependent variable is response time (RT). I want to transpose the data to a form suitable for MANOVA such that there is one observation per subject and RT is recoded across many

Hello, I am new to R and currently have the following problem: I have successfully loaded my data in R which consists of two numeric columns (LI_F and female) and one character column (Strain). So far I can plot two different set of boxplots for each of the numeric columns plotted by the groups of the character column and the commands look like that: boxplot(LI_F~Strain, ylab="LI_F",

Hello everyone, Source, binaries and docs for LLVM-5.0.0-rc2 are now available at http://prereleases.llvm.org/5.0.0/#rc2 (I'll add more binaries as they become available.)
