similar to: How to remove all objects except a few specified objects?

I noticed the new environmentName in R 2.5.0dev. Thus I gather that each environment has: (1) a name (2) a hex value so 1. environmentName gets the name. Is there any way to set the name? 2. is there any way to get the hex value for an environment other than doing: e <- new.env() capture.output(e)

Hello All, ?environmentName shows how to get the environment name. But I don't see how to set the name in the first place. Could you tell me where to look for the function that set the environment name? -- Tom

Dear R-Devel, I was attempting an exercise in Hadley Wickam's book "Advanced R". The exercise is to find the generic with the greatest number of methods. I found that 'methods(`|`)' produces a list of length 2506, in R 3.3.1. Similar behavior is found in 3.4.0. It seems to include all functions and methods. I imagine something is being passed to "grep" without

Hi, from the man page ?methods, I expected to be able to build pairs (class,package) for a given S3 method, e.g., print, using attr(methods(print), 'info'). However all the methods, except the ones defined in base or S4 methods, get the 'from' value "registered S3method for print", instead of the actual package name (see below for the first rows). Is this normal

Dear all, I would like to know if there is a R package performing model identification? thank you! -- View this message in context: http://r.789695.n4.nabble.com/R-package-to-identify-model-tp2529525p2529525.html Sent from the R help mailing list archive at Nabble.com.

Dear all, seems that easy question but cannot find the function for that. How to get the elements of the minor diagonal of the matrix? Thanks a lot. [[alternative HTML version deleted]]

I suppose it would work, although "=>" is rather a descriptive symbol and less a function. But choosing between quoting: "A + B => C" and a regular function: A + B %=>% C probably quoting is the most straightforward, as the result of the foo() function has to be a string anyways (which is parsed by other functions).

Dear all, I have a problem with the cat() function. Let say I have following: fn1 <- function(n = 5){ mat <- matrix(rnorm(5*5), 5, 5) cat(as.character(mat)) return(n) } However when I run above function I get this: > fn1() -0.601930631438248 -1.16950049447942 0.469257329394626 -1.39766868242906 -1.02580943892082 1.4067931110327 -1.07245318857022 -0.0205043699310245 0.234628727206755

%=>% would have precendence ('order of operations') problems also. A + B %=>% C is equivalent to A + ( B %=>% C) and I don't think that is what you want. as.list(quote(A + B %=>% C)) shows the first branch in the parse tree. The following function, str.language, shows the entire parse tree, as in > str.language(quote(A + B %=>% C)) `quote(A + B %=>%

After seeing a recent proposal by Gabor Grothendieck I came up with the following solution, display <- function(...) { my_names <- lapply(substitute(placeholderFunction(...))[-1], deparse) for (my in my_names) cat(my, "=", eval(parse(text=my)), "\n", sep=" ") } that works about as

Dear All: I would like to know if there is plausible way to say to R to remove all elements in the memory but the sequence. I have a code which makes a loop, and what I want is after the programme has performed all the operation over every "i"th element, to remove all the objects, expect the sequence parameter. I included the option "rm(list=ls(all=TRUE))", but obviously that

Hi, I've just created: newEnvEval <- function(..., hash=FALSE, parent=parent.frame(), size=29L) { envir <- new.env(hash=hash, parent=parent, size=size); evalq(..., envir=envir); envir; } # newEnvEval() so that I can create an environment and assign objects to it in one go, e.g. env <- newEnvEval({ a <- 1; b <- 2; }); print(env$a); Does this already exists somewhere?

Thanks Kevin, this indeed clarifies a bit the S3 method registration universe.

Hi [R-2.10.0; suse linux] I am having difficulty creating S4 objects in the data directory of a package. I want to create a bunch of simple S4 objects for use in the examples section of the Rd files. It says in R-exts that: " R code should be ?self-sufficient? and not make use of extra functionality provided by the package, so that the data file can also be used without having to load

Hi all, I have following environments loaded with my current R session: > search() [1] ".GlobalEnv" "package:stats" "package:graphics" "package:grDevices" [5] "package:utils" "package:datasets" "package:methods" "Autoloads" [9] "package:base" How can I find the objects

Can please someone familiar with the R internals explain on the following: PR#1434 from r-bugs clarifies that assign("a[1]", x, SomeOtherFrame) or assign("a$a", x, SomeOtherFrame) will NOT assign to an object 'a' in the other frame BUT create a new object called 'a[1]' resp. 'a$a'. This leads to the following question: what is the most
