Hello List, I've done some cursory searching but (so far) have struck out. Does anyone know if the R version of the S+ FinMetrics package is available? Best, Bill Vedder

Greetings, I wonder if someone could point me towards a more elegent solution than what I"ve kluged together. I have a vector "samp1" of 296 integers. They are sorted in ascending order and the numbers range from 177 to 228,953. I'd like to specify N non-overlapping intervals covering the range from 0 to 229,354 and then for each range, count the number of integers from samp1

Dear MCMCglmm users, I am currently struggling with the specification of a proper prior and model formula for a multi-response MCMCglmm with two of the three response variables being Gaussian and the third being za-poisson. The model includes several fixed effects and three nested random effects. In general, I would prefer to fit a model with a fixed effect of trait and suppressed intercept for

Hello, I have a C++ code for 2D random walks with traps and I want to convert it in a R code with its syntaxs, can anyone help??????? It's easy for me to adapt the body but I want help with the beginig (variable declaration) and th end exporting the output to a file ( like write.table() or sink() ) Thank you... #include <iostream> #include <math.h>#include

Good Evening, I'm using R1.2.1. Is 3D plotting available? The only reference I find is to "plot.locfit.3d {locfit}" and the documentation says the function is not currently available in R. Any help is appreciated. Best Regards, Bill Vedder -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Hello, I'm new on this list. First of all, thank you to all the developers of this great project! At the moment there is only an application that keeps me on both macos and windows, its name is PWGL a free environment for computer assisted composition in openGL. (http://www2.siba.fi/PWGL/) I'm running Ubuntu 8.04 and wine 0.9.59. I have to say that I also installed vcrun2005 and

I saw an example online of taking hclust dendrogram and plotting it using ggplot2 and thought I would give it a try to see what it would look like. I get an error when trying to use ggplot; Error: ggplot2 doesn't know how to deal with data of class phylo. Regular plot works fine but I can't get ggplot2 to work. see code below.... rows=100 columns=100 #create matrix

Greetings RListers, I have a data set containing two types of outcomes; success and failure. Associated with each outcome are 12 different measurements. I'm trying to find out, for example, if some of the 12 measures are associated more with success or failure or, if there's any relationship at all between the measures and the outcomes (success or failure). I don't have (as yet)

Hi, what is the proper of of "passing a missing value" so I can extract the entire i-th row of a matrix (in a list of lists) without pre-computing the number of cols? For example, if I know that the matrices have 2 columns, I can do the following: set.seed(1) x0 <- lapply(1:10, function(i) replicate(4, list(matrix(rnorm(10), nc=2)))) lapply(lapply(x0, '[[', 3), '[',

Greetings R-Listers, Using R1.2.1 (yes, I know...) I am writing my own functions and would like to know how save these for use in subsequent R sessions. How does one do this?

Hello guys, I have a list L1 of matrix. I have another list L2 with the same number of elements representing the row of the L matrix that I want to delete (L1[[i]][-L2[[i]],]) but I can't do this with lapply as it iterates through L1 (first argument) and not L2. Any idea? ----- Anna Lippel -- View this message in context:

Hey there, I've got a list of lists with matrices: A list with 13 entries (representing years), each of them another list with 12 matrices (representing one month). In each matrix there are as many rows as there are hours in the different months and 2 columns, since two meteorological parameters are measured. What I want to do is to calculate the hourly mean values for each month over the

Hello, I have 2 functions (a and b) a = function(n) { matrix (runif(n*2,0.0,1), n) } > > > b = function (m, matrix) { > n=nrow (matrix) > p=ceiling (n/m) > lapply (1:p, function (l,n,m) { > inf = ((l-1)*m)+1 > if (l<p) sup=((l-1)*m)+m > else sup=n >

Hello R-Helpers, I have a slight problem with the expresion data[data==""] <- NA which works well for a data.frame. But now i must use the same for a list of data.frames. My idea is data[[]][data==""] but it don´t work. Thanks!! Dominic [[alternative HTML version deleted]]

Dear R users,I have a list of equally structured lists, how can I access e.g. all 2nd compontents in those sub-lists?An example:lst <- list(rep(list(1:3),3), rep(list(4:6),3))> lst[[1]][[1]][[1]][1] 1 2 3[[1]][[2]][1] 1 2 3[[1]][[3]][1] 1 2 3[[2]][[2]][[1]][1] 4 5 6[[2]][[2]][1] 4 5 6[[2]][[3]][1] 4 5 6What I want to get are all second sub-lists, in this case:[[1]][[2]][1] 1 2

Happy Holidays All, I'm trying to use stl() to extract a seasonal component from a time series. I believe the root cause of my problem lies in how I imported the data into R. In Excel (csv), the data look like: Jan Feb Mar .... 1949 12.2 9.0 7.9 .... 1950 17.2 16.9 9.9 .... 1951 8.2 7.0 7.7 .... I import to R using:

Hi All, I'm trying to understand the difference between do.call and lapply for applying a function to a list. Below is one of the variations of programs (by Marc Schwartz) discussed here recently to select the first and last n observations per group. I've looked in several books, the R FAQ and searched the archives, but I can't find enough to figure out why lapply doesn't do what

DeaR useRs: I have a list with 500 elements, in each other there are data.frames and I want to take the first row and the first column of each elements of my list since the first to the 500-th. Thanks and excuse my bad English. --- [[alternative HTML version deleted]]

Good evening I often have as output from simulations a list of various values, vectors and matrices. Supposing that I then run said simulation several times, I often want to extract a particular result from each simulation for plotting and, ideally, put it in a matrix. A simple example v1 <- 1:5 v2 <- 6:10 other1 <- "stuff" other2 <- "stuff" set1 <-

x=list(a=c(1,2),b=c(3,4,5)) y=list(a=c(1,2),b=c(3,4,5)) lapply(seq(along=x),function(i){cbind(x[[i]],y[[i]])}) I need to apply some function on two lists. I have to use the index to do as shown above. But I feel more natural to refer to the lists without using the index (using the syntax of something like, lapply(x,y, function(i,j){....})). I'm wondering if there is such a thing in R? Or
