Hello, I would like to sample a population but the result needs to be reproducible, using 'runif' or 'sample' is the good way to do it but I can't manage to make the results reproducible even with the 'set.seed' function. My aim is that th call to 'sample(1:100,10)' gives always the same result, how can I do that? Thanks! Eric Esposito

I have used Splus 3.4 for UNIX and I have a C file that I compiled using "Splus COMPILE" and later called with dyn.load() and .C(). It works in Splus. I want to do the same thing in R, as in just use my .s and .c files and find the equivalent of "Splus COMPILE". I've ran into lots of problems trying to do this in Windows so far, so please help! My questions are: - Do

Hi, Suppose I have created something like this in R: foo <- "myfoo" and I want to find out the number of character in foo (in other words, R should return 5 since "myfoo" has 5 charactors. How can I do it? I tried: length(foo) but it returned 1. Cheers, Kevin ------------------------------------------------------------------------------ Ko-Kang Kevin Wang

Hi, Is it possible to add a subtitle that appears directly below the main title? I tried the "sub" parameter, but it adds sub-title to the bottom of the plot.

Hi, I think I found the problem. It lies in my Fortran program. Is there a way, after a DO loop, to make sure it does NOT return anything?

Hi all, I'm new to R and am trying to create a dll in order to be able to use the "dyn.load" function with a fortran script. I have a windows OS, have installed perl and the Path is recognized. I have also installed R 1.70 including the src (source code) folder. But when I attempt to create the dll by excecuting "Rcmd SHLIB [-o autologdll] combo.f", in the windows

I have just got a new machine and had a basic cygwin installed before it was given to me. It didn't include make. Previously I have installed Rtools to build packages and now I have got myself a bit confused as to whether to just install make from the cygwin packages or to install rtools. I would welcome any advice. I had a look at the rtools section in the Administration Manual and the

Hey, R-listers I was recommended to try using smooth.spline function for estimating 2-Dimensinal curve given a data set. So will you please tell me where to get this R function? Or which package provides this function? Thanks for your point. Fred

Hi, Say I want to do something like fitting 10 different sized trees with rpart() function. The only modification I need to do is to set 10 different cp's, which I have in a vector called foo. Can I do something like: for(i in 1:10) { rpart(y ~ ., cp = foo[i], data = mydata) } My problem is, I wish to save the 10 rpart objects into 10 different names, my.rpart1 ~ my.rpart10, for

Hi, Say I did something like: par(mfrow = c(1, 2)) plot(1:10) plot(1:10) and I'd like to have an overall title, i.e. a title that would appear, centered, on the top of both plots, rather than the top of the last plot. I tried: title("FOO", outer = T) but it doesn't appear right. Half of the FOO is outside the figure region and can't be seen... Is there another

Hi, Now suppose I have just one list called FOO, which has 25 objects, e.g.: [[1]] 1 2 3 4 5 [[2]] 6 7 8 9 10 . . . And I want to do something like: FRED <- data.frame(cbind(unlist(FOO[[1]]), unlist(FOO[[2]]), # ... for all 25 subsets )) Is it possible to do this, without doing unlist(FOO[[i]]) 25

Hi, I have a column in a dataframe in the form of: > as.vector(SLDATX[1:20]) [1] "1/6/1986" "1/17/1986" "2/2/1986" "2/4/1986" "2/4/1986" [6] "2/21/1986" "3/6/1986" "3/25/1986" "4/6/1986" "4/10/1986" [11] "4/23/1986" "4/30/1986" "5/8/1986"

Hi, I'm a bit confused how julian() works. If I understand right, it returns the number of days since the origin. I have a vector: > SLDATX[1:10] [1] "1986-01-06" "1986-01-17" "1986-02-02" "1986-02-04" [5] "1986-02-04" "1986-02-21" "1986-03-06" "1986-03-25" [9] "1986-04-06"

Hi everybody. I'm a new R user and i've been searching a tool for construction of regression tree... I found function "tree()" written by a certain Mr. Ripley, and seems to be just what i'm looking for, but when i try to use it in R replies me:"Object not found". So I was wandering if I should include one special library or something like that? Thanks a lot, ana

Hi, If I have: foo <- survfit(y ~ x) where y is a survival object and x is a n-level factor. The documentation says when I plot(foo), the confidence intervals will not be plotted (which I guess is understandable as otherwise the plot will get really messy). I tried to plot with confidence intervals by using: plot(foo, conf.int = TRUE) and indeed the resulting plot is messy. However

Hi, I'm not sure if this can be done but.. I know that with ifelse() I can do something like: ifelse(x <= 3, 1, 2) to go through each element in my vector x, and if x_i <= 3 substitute the number with 1 else with 2. Essentially I'll get a vector with 2 levels. Can I tweak it so I can get 3-levels? For example: if(x <= 3) then 1 elseif(3 < x <= 4) then 2

R 1.6.0 has gone into final feature freeze as of today. As a new feature, we'll make interim beta versions available via ftp://cran.us.r-project.org/pub/R/src/base alias http://cran.us.r-project.org/src/base (filename R-1.6.0beta_*.tar.gz, where * is the creation date). If you want to help ensure that the final 1.6.0 works satisfactorily on *your* platform, it might be a good idea to

Hi, Is it possible to draw barplot with x-axis being shown? I looked up the help file and I couldn't seem to find it. For example, I tried to do x <- 1:9 p <- log10(1 + 1/x) barplot(p, xlab = "Digit d", ylab = "Probability", ylim = c(0, 0.35), axes = F, main = "Benford's Law Probability") axis(1, 1:9) axis(2, seq(0, 0.35, by = 0.05),
