Hi all, Is it possible to add a permil (or per mille) symbol to an R plot (I couldn't find this symbol under demo(Hershey) or the plotmath information). In some ascii tables it is symbol no. 137. cheers, Matt. [[alternative HTML version deleted]]

Hi R-listers, I am trying to better undertand what we would call "functional paradigm" use of S/R to better map my programming activities in other languages. This little function is aimed to create an object (at the end end, it would have it's own class): -- myObject =function(){ list( a=1, foo=function(b) { cat("b:",b)

Hello UseRs: Excuses for my english. I have a dataset with 65000 records and I'd like to make a summary where I can view all the values (with the number of times that it repeats) that there are each column of my dataset. I tried with summary( ), str( ), but nothing gives me the result that I am loking for. Thank you very much.

Hi, I need to parse a data file (output of a measuring device) of the following format: BEGIN RECORD [first record data] RECORD [second record data] RECORD [third record data] END Line breaks can (and do ;-() occur anywhere. White space behaves very much like TeX, eg it is not important whether there are one or more spaces or linebreaks as long as there is one of them. It is a text file, not

Hi users, I am not sure to understand the help page about do.call. -- do.call(what, args) args: a _list_ of arguments to the function call. The 'names' attribute of 'args' gives the argument names. -- If we take the following sample data: > (tab=as.data.frame(table(factor(1:10)))) Var1 Freq 1 1 1 2 2 1 3 3 1 4 4 1 5 5

Hello, I would find it very usefull to have the ability to load packages with options. Consider for example the SciViews package Philippe and me are working on. When loading on Windows, it automatically loads the associated GUI executable. It should be convenient to have an option not to load the exe but still have an access to the R functions of the package. For that, I think a simple change

Hi, I would like to know if people have found the package made4 to load! I would like the .zip If you have the @ on internet to load it please give me it! Thanks a lot, Sabine --------------------------------- [[alternative HTML version deleted]]

Dear R users; I would like to convert a series of vectors to matrices in the following way; (2,1,1) to a matrix 1 0 0 1 0 0 0 1 0 0 0 1 The idea is that the column sum of the matrix should be equal to the elements of the vector. Thanks. Vumani

Dear list, I would like to rename an object as follows: SimLUall <- matrix(c(0,1,0,0, 1,0,0,0, 0,0,1,0, 0,0,0,1),nrow=4, ncol=4) j <- 2 SimLUall2 <- SimLUall and j The value of j should be assigned automatically to SimLUall. How can I achieve this? Regards, Ulrich

Hello I am able to extract partial regression coefficients from a fitted model object "model", i.e. model <- lm(var.sel.gkm, weights = count.gkm, data = DATA) summary(model) write.table(model$coef, file = "C:/coef_CO_gkm.txt", row.names = TRUE, col.names = TRUE) I was wondering if anyone could advise me how to extract other object items such as std. error, t-values

Hello R-World, i am trying to calculate data for a DEM (Digital Elavation Model) which i also want to plot in R. i have the coordinates for the lower left corner which look something like this: x<-42,2 y<-50,5 besides i have the cellsize of the grid, which is: z<-1,1 what i do is to calculate the corrdinates of the cells to the right and top, what i can do by specifying the number of

Hi R-devel, If you did read my survey on Rhelp about reporting, you may have seen that I am implementing a way to handle outputs for R (mainly target output destinations: xHTML and TeX). In fact: I does have something that works for basic objects, entirely done with S4 classes, with the results visible at: http://www.stat.ucl.ac.be/ROMA/sample.htm http://www.stat.ucl.ac.be/ROMA/sample.pdf To

Hi - platform powerpc-apple-darwin6.8 status major 1 minor 9.0 year 2004 I am trying to deal with the output of apply(). As indicated, when each call to 'FUN' returns a vector of length 'n', then 'apply' returns an array of dimension 'c(n, dim(X)[MARGIN])'. However, I would like this to be a list in the same format as is produced when 'FUN'

How can I get a multi line string from a vector of string tokens in an easy manner (e.g. for the use as xlab of a plot)? I have e.g.: > tokens <- letters[1:5] [1] "a" "b" "c" "d" "e" I search: [1] "a, b, c\nd, e" I tried: > nlines <- 2 > ntokens.line <- ceiling(length(tokens) / nlines) > token.list <-

I have a matrix that I want to turn into a transformed matrix that includes the indices from the original matrix and the value. The matrix is simply real-valued and is square (and large (8k x 8k)). I want something that looks like (for the 3x3 case): i j value 1 1 1.0 1 2 0.783432 1 3 -0.123482 2 1 0.783432 2 2 1.0 2 3 0.928374 and so on.... I can do this with for loops, but there is

Hi, is there any way to keep a sub matrix dimension? exemple : i1<-1; i2<-1 j1<-2; j2<-3; ret <-matrix(1,4,4)[i1:i2,j1:j2] ; dim(ret) is NULL because the submatrix single col or single row is coerce to a vector automaticaly. How can i bypass this cast : submatrix->vector ??????? Thank you. --------------------------------- [[alternative HTML version

Hello R Power Users, There is a rather large introduction you may skip to go directly to my question about S4 classes. I am working on some toy code to help me get in through S4 classes. Doing this homework, I have some questions about S4 classes. I have carefully read available help and some additional material such as Robert Gentleman's slides and special attention to "Programming

Hi I need to define the following c("one group" = class.weight[2], "other group" = class.weight[1]) #class.weight = c(1,2) but I don't like the hard-coded way and would like to use my.group <- array(c("one group", "other group")) but now c(my.group[1] = class.weight[2], my.group[2] = class.weight[1]) gives an error how can I solve this

Suppose I have f1 <- function(x) x f2 <- function(x) x^2 funlist <- list(f1,f2) Then I would like to evaluate funlist such that when x is 10 I should get a list with 10 and 100. A naive way of doint this is myf <- funlist[[1]] do.call(paste(quote(myf)), list(x=10)) myf <- funlist[[2]] do.call(paste(quote(myf)), list(x=10)) - but there has to be much
