Hi Everyone, After searching the subject and not being successful, I was wondering if any you could explain me the idea behind the following fact: all(NULL == 2) ## TRUE any(NULL == 2) ## FALSE Thanks a lot, Benilton -- Benilton Carvalho PhD Candidate Department of Biostatistics Johns Hopkins University

Hi everyone, sorry if this was discussed before (and in this situation, could you please point me to the discussion in the archive? My search didn't seem to be effective). Is there a way of getting the names of objects in a .rda file without having to load it?

...files is something I'm not in a position to interfere with, are there (preferably, "all in R") suggestions on how to handle such task?

...d(tmp0, c(d=NULL)) ## list with a/b/c only Given that I could use tmp0$a <- NULL to remove 'a', I seem to understand why appending NULL returns me the original list... But how should I proceed to actually have d=NULL (just like I have 'b' in tmp0 above)? Thank you very much, benilton

Dear All, I am attempting to set up Samba 1.9.18p8 on a Sun E450 running Solaris 2.6. The Sun is configured as a NIS master serving a number of other Unix machines. It is our primary development platform acting as a NIS client and also has auto mounted home directories for users.

Hi to all, I found in the R-help archive how to calculate the p-value for a gee result: http://finzi.psych.upenn.edu/R/Rhelp02a/archive/74150.html but there are two questions (I am afraid they are basic questions ...) 1. why is the result multiplicated with 2 2. how could I decide between lower.tail =TRUE and FALSE: example:

...Not long ago, there was a discussion about building Windows packages from the source code and someone posted a link to a website to which we could submit the source and get the Windows version a while later.

...y(1:10, function(i) replicate(4, list(matrix(rnorm(100), nc=sample(c(2, 4, 5, 10), 1))))) what would be the value of J below? lapply(lapply(x1, '[[', 3), '[', i=2, j=J) or should I really stick with: lapply(lapply(x1, '[[', 3), function(x) x[2,]) ? Thank you very much, benilton

...sses?, already loading ?oligoClasses? I don't see anything obvious in the name space that would indicate cyclic dependency and I wonder: a) if there were changes that were meant to affect this; b) what is the recommended strategy to solve this issue.

...umentation for dimnames(), it states that if value is a list "its components are either 'NULL' or a character vector with positive length of the appropriate dimension of x". Should dimnames() return an error on the example above? Thank you very much for your attention and time, benilton

...ind+lapply combo above? On this example, the combo takes roughly 20s on my machine... but on the data I'm working with, it takes more than 1 minute...

...;[' and I wonder if someone could point me to the right direction: 1) Call the S4 object "obj" 2) Assume dim(obj) = c(10, 4, 2) 3) Suppose someone calls: obj[1:3,] , which is a mistake, given dim(obj); how do I detect such situations? Thank you very much for your attention and time, benilton

Dear all, Happy new year! I posted a very similar question a few days ago, but probably too cluttered. Here is a tidy, minimal version: I want to make a package, with a data.frame d and a function f given below. Now, the function f needs to use the data.frame d. I could (and that's what I've done temporarily) make a local duplicate of this data.frame in the function definition,

Hi Everyone, I want to generate some random numbers according to some empirical distribution. Therefore I am looking for the inverse of an empirical cumulative distribution function.
