Dear R Gurus: How do I find the functions which are primitives, please? Thanks, Edna Bell

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

Dear R-users, Is there a way to test whether a particular environment e is equal to emtyenv(), or for that sake whether two environments e1 and e2 are equal? I tried a couple of ways to compare environments, but neither seem to work: > e1 <- new.env() > e2 <- new.env() > e1 == e2 Error in e1 == e2 : comparison (1) is possible only for atomic and list types > all.equal(e1,

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

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

Hi R-devel, The following code: all.equal(baseenv(), baseenv()) gives the error when run in a clean R session with latest R-devel (r66650): kevin:~$ R --vanilla --slave -e "all.equal(baseenv(), baseenv())" Error in all.equal.envRefClass(target[[i]], current[[i]], check.attributes = check.attributes, : attempt to apply non-function Calls: all.equal ...

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

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! 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? Thanks, Edna Bell PS I can't seem to access the "Writing R Extensions" manual from 2.6.1 on Windows.

Hi, this relates to the question "How to set a former environment?" asked yesterday. What is the best way to to return a function with a minimal environment from a function? Here is a dummy example: foo <- function(huge) { scale <- mean(huge) function(x) { scale * x } } fcn <- foo(1:10e5) The problem with this approach is that the environment of 'fcn' does not

Dear R gurus I would like to take a monthly time series and convert it to a data frame without losing the tsp items, pleae I've tried as.data.frame and data.frame but I get the series without the time element. Any suggestions, please? tia 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

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

I wish I had started with "I am disappointed that lm() doesn't continue its search for weights into the calling environment" or "the fact that lm() looks only in the formula environment and data frame for weights doesn't seem consistent with how other values are treated." But I did not. So I do apologize for both that and for negative tone on my part. Simplified

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

Dear R Gurus: Is there a test for a single variance available in R, please? Thanks, Edna Bell

I've just committed some changes to R-devel which affect environments. Specifically: - using NULL as an environment is now deprecated: use baseenv() instead. (baseenv() is already available in R 2.2.0, where it returns NULL. For most purposes it retains the same meaning in R-devel.) If you do use NULL, it will be converted to baseenv(), and a warning printed. For example: > f

Dear R Gurus: I'm trying to find R on another Linux system. I'm using the find command, (surprise), but I only want to see the output where it exists, not all of the other stuff. Is there an option that I could select, please? Right now I have find / -name R TIA, Sincerely, Edna

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

Hi! What is the difference between using data(somedataset) vs. attach(somedataset), please? thanks, Edna Bell
