hi all, how can I create sequences that start from a known vector, say x1 and end with another say x2- also suppose all the sequences will be the same length. I don't want to use a for loop x1<-c(1,2,3,4); x2<-(3,4,5,6); what I want is 1 2 3 4 2 3 4 5 3 4 5 6 Thanks ----- Yasir H.

Hi, How can I generate a random signal that's correlated with a given signal at a given correlation (say 0.7)? I've been looking at rmvnorm etc but don't seem to figure it out. Thanks ----- Yasir H.

I have a text file like this 2.5 3.6 7.1 7.9 100 3 4 2 3 200 3.1 4 3 3 300 2.2 3.3 2 4 I used "r <- read.table("a.txt", header=T)" The row names becomes X2.5, X3.6... What I need is the row names are numeric, so I can use the row names as numbers on x-axis for plotting. e.g. "plot(colMeans(r)~names(r))",

Hi, I have 2 questions about bwplot in R : 1) How to change the order of my different boxes in the graph ? 2) How to rename the names of the differents boxes ? because I know how to do that with boxplot (using names) but I do not find the equivalent parameter in bwplot. thanks, C?dric

Hi, I am having a situation where I cannot change the output size of the R console. I have played around with the font format menu but the changes are only reflected to the script that I type in but not to the output. Everytime I run a script, I have to go back to font format to increase the output script, which is currently showing up as small as the dust on my computer screen. I have mac by

The Runuran package includes a simulation for the Triangular Distribution, urtriang. But I didn't find an analogue of the q* functions (rnorm - qnorm, runif - qunif), that would invert the CDF (?uqtriang). Are there any such functions? Alberto Monteiro

Hi All, I performed an svd on a matrix X and saved the first three column of the left singular matrix U. ( I assume that they correspond to the projection of the matrix on the first three eigen vectors that corresponds to the first three largest eigenvalues). I would like to know how much variance is explained by the first eigenvectors? how can I find that. Thanks for your help -- View this

I'm trying to write R functions into VBA code. I've done this many other times in other documents and everything has run great. But today I keep recieving an error message "Run-time error '1004': Application-defined or object-defined error." Has anyone else encountered this same error message? I do not recieve this error in the document when running regular VBA code.

Hi list, Does anyone know if there is a library in R that does MTM-SVD method for spectral analysis? Thanks ----- Yasir H.

Hi all, I'm new with R, recently I began to use the package "arulesSequences" but the algorithm cspade give me this error: Error en makebin(data, file) : 'sid' invalid when I did executed this script, x = read_baskets("transactions.basket",sep=",",info=c( "eventID", "sequenceID","SIZE")) s <- cspade(x, parameter =

Hi, I have a list called ds which has the following attributes: attributes(ds) $names [1] "adj.r.squared" "fstatistic" "intercept" "slope" [5] "std.error" "tstatistic" I want to replace all the NaN is ds with 0, and after searching past posts I found I can hardcode it like this:

Dear All, I want to change file names. I have file0.1_data.RData (I have several files whose names are file0.x_data.Rdata) I want to rename it to file1_data.RData How can I do it? Thank you for saving my time! [[alternative HTML version deleted]]

I have time series data in named vectors. They are all the same length for the same dates. The dates are in a separate vector. I want to create a vector of numeric data for every named series, associated with the dates in a data.frame. So if... Names <- c("a", "b", "c") d <- data.frame(dates=Dates, a=vector(mode="numeric", length=length(Dates),

Dear Nabble. I am trying to draw a box percentile plot with trellis using the panel in Hmisc. I really want to colour the plots in. I can alter several of features of the plot by changing the trellis par settings but I just can’t fill the shape in. Here is some example code which alters line colour and dot symbol: require(lattice) require(Hmisc)

Hi R users: I will like to know if somebody works on insurance statistics (actuarial problems) and had use TRICAST, and can tell me if with all the R tools it can be build a solution like TRICAST or similar. In a word: Do you think that R has all the statistical tools (I mean modeling tools) to make a job similar to TRICAST? Does TRICAST has modeling tools that are not implemented on R yet?

Hi I would like to know how to pivot a table that will sum the number of plants (a or b) for each location (x,y,z) I have read on the listserve similar questions but which involve summing up numbers rather than factors. I have also read about the R package reshape on the listserve but wanted to know if there's a way to do it easily without the package Thanks for the help! location plant x

Hi! (a complete newby, but will not give up easily!) I was wondering if there is any way to decouple the axis and tick mark widths? As I understand they are both controlled by the lwd setting, and cannot be controlled independently? For example I might want to create major and minor ticks, which I now know how to do by superimposing two axes with different at settings, but what if I also wanted

Hi, I'm new to R and this mailing list, so I will attempt to state my question as appropriately as possible. I am running R version 2.7 with Windows XP and have recently been exploring the use of the function regsubsets in the leaps package in order to perform all-subsets regression. So, I'm calling the function as:

Dear R users, I want to calculate the bias and variance of an estimator for several values of two parameters a and b. For example : b1 b2 a1 bias bias variance variance a2 bias bias variance variance Can one do array of arrays ? I have tried and it did not work. Actually I would like to get this array for several values of the number of observations. That
