Hi R Gurus! This is definitely off topic, but I thought I'd try: what is the way to put in url's into a Latex file, please? I know that you start with a \newcommand statement, with some kind of argument that will change, but I'm not sure how to set it up, please. thanks, Edna Bell

Hi again! Suppose I have the following: > xy <- round(rexp(20),1) > xy [1] 0.1 3.4 1.6 0.4 1.0 1.4 0.2 0.3 1.6 0.2 0.0 0.1 0.1 1.0 2.0 0.9 2.5 0.1 1.5 0.4 > table(xy) xy 0 0.1 0.2 0.3 0.4 0.9 1 1.4 1.5 1.6 2 2.5 3.4 1 4 2 1 2 1 2 1 1 2 1 1 1 > Is there a way to set things up to have 0 - 0.4 0.5 - 0.9 etc. please? I know there is the cut

Dear R Gurus: I read somewhere that functions are considered vectors. Is this true, please? thanks Edna Bell

Hi R Gurus! I have a package that I am putting together. I waited until the end to do the documentation and would like to generate a set of "empty" .Rd files. Is there a quick way to do this, please?

Dear R Gurus: Is there a problem with Rmpi on x86 with SUSE 10.1, please? I've tried everything and it still won't load. Has anyone else dealt with this please? Thanks, Edna Bell

Dear R Gurus: How do you put together a 2^2 (or even 2^k) factorial problem, please? Since you have 2 levels for A and B, do you put in "A+" and "A-" as factors, please? Thanks, Edna Bell

Hello R Gurus: I would like to take a character string and split at the $ sign. I thought that strsplit would do it, but here are the results: > vv [1] "whine$ts1" > vv [1] "whine$ts1" > strsplit(vv,"$") [[1]] [1] "whine$ts1" Does anyone have any suggestions, please? Thanks, Edna Bell

Hi R Gurus! I have 2 questions, please: a. I'm putting together a little baby package on SUSE Linux 10.1. I want to create a zip of the package for windows. How should I create that please? b. I don't know if the following is possible but here it is: I have R and a bunch of libraries set up very nicely. I would like to hand off this setup to someone else. Should I just copy

Dear R Gurus: I'm working slowly through "R Programming for Bioinformatics", which is really interesting! Anyway, my question now is: what determines if a function is a builtin vs. a closure, please? For instance: > typeof(sqrt) [1] "builtin" > typeof(mean) [1] "closure" > Thanks, Edna Bell

Hi R Gurus! I'm trying to create a test package using the package.skeleton function. I wanted to add some compiled code too. In the src library, I put together a baby subroutine, compiled it and created a test.dll When I use the R cmd build, it works fine. But I get into trouble with the R CMD check section. /home/Desktop/R-2.5.1/bin # ./R CMD check mypkg * checking for working latex ...

Hi R Gurus: Here is some code that I was experimenting with, please: > f1 <- function(x) { + e1 <- new.env(parent=.GlobalEnv) + environment(e1) + print(environment()) + return(mean(x)) + } > f1(1:15) <environment: 0x02525444> [1] 8 > My question: why isn't the environment within the function set to e1, please? Thanks, Edna Bell

Hi R Gurus: I have a tiny data set: > xs [1] 0.7 2.8 0.1 1.9 0.0 1.4 0.2 2.3 0.3 0.2 > and generate the density function for it. I would like to replicate this. Is there a straightforward way to do this, please? According to the help file, the FFT is used. How does this compare to Silverman's version from his page 15 Equation 2.2a, please? Thanks, Edna Bell

Hi! Suppose I have a factor: > fac1 <- factor(rep(c("dog","cat","tree"),c(2,3,4))) > fac1 [1] dog dog cat cat cat tree tree tree tree Levels: cat dog tree > length(fac1) [1] 9 Now I want to get rid of the dogs: > fac1 <- fac1[3:9] > fac1 [1] cat cat cat tree tree tree tree Levels: cat dog tree > How should I remove the dog from the

I have put together a test class and methods > setClass("foo",representation(x="numeric")) [1] "foo" > setMethod("plot","foo",function(x,y,...)boxplot(x,...)) [1] "plot" > x <- rnorm(100) > class(x) <- "foo" > plot(x) > y <- new("foo",x=rnorm(50)) > class(y) [1] "foo" My

Dear R Gurus: I vaguely remember reading that if interaction was present in a factorial design, then the main effect results were suspect. However, I was reading a text which now uses the tests for main effects even if interaction is present. Which is correct, please? Thanks, Edna Bell
