similar to: Set environment name

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)

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

Hello All, If I refer to a variable 'x', 'x' will be searched in the current frame or the parent frame, or the parent of the parent frame, etc., until it is found (or not found at all)? Could you please show me what code in R source that handles this? Is it in the C code or the R code? Thanks, Tom

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

I would be very glad of pointers to information on how the concepts of packages, namespaces and environments are interrelated in R. I am trying to get a handle on this both so I can delve further into understanding other people's code and so I can organize my own in a more coherent manner. From my reading about environments it seems they function as what I would intuitively call

Hi. contrary to other environments, the attributes of a *package* environment are dropped (from the new environment) when attach():ing it to the search() path. This might or might not be surprising, but have some side effects if rearranging/attaching package environments. # Example - Regular environments env <- new.env() attr(env, "foo") <- "bar" print(env) ##

Dear All, I want to check what packages depends on a given package. For example, glmnet depends on Matrix. I want get the names of all the packages that depend on Matrix on CRAN. Is there a way to do so? Thanks! > library(glmnet) Loading required package: Matrix Loading required package: lattice -- Tom

%=>% 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 %=>%

Hi, When I create an environment object with new.env() and populate it with values then how can I save it into an .RData file properly, so it can be loaded later on in a new session? Saving an environment object with save() or save.image() results in an error message when loading again: Error: protect(): protection stack overflow Regards, benjamin ======================================

Hi I wondering if its possible to make a hidden environment for a package, so the user cant see whats in it but the diffrent functions inside the package can use the variables in the environment.

Hi, 'R CMD INSTALL -l' will stop if some error is encountered. I don't find in the manual an option to keep the command running. Is there such an option? -- Tom

I have a class defined as an extension to matrix: fooCLASS <- setClass("foo",representation("matrix")) and define a method for a generic function (no problem): setMethod("diff",signature(x="foo"),diff.foo <- function(x){x}) but I get a different behaviour for another generic function: setMethod("lag",signature(x="foo"),lag.foo

All, For those that are using external nodes (as local files) and multiple environments, where do you put the external node files? Ie, do you put them down in the environment itself /etc/puppet/env/env1/manifests/extdata/nodes /etc/puppet/env/env.../manifests/extdata/nodes /etc/puppet/env/envN/manifests/extdata/nodes OR, up above the environments? /etc/puppet/manifests/extdata/nodes Which

Last week Giovanni Parrinello posted a message asking why various packages were loaded when he loaded an .Rdata file. Brian Ripley replied saying he thought it was because the saved workspace contained a reference to the namespace of ipred. (Correspondence copied below). This begs the question: how did the reference to the namespace of ipred come to be in the .Rdata file? Brian did say it is

I noticed the following today --- str() seems to remove any extra class information added to an environment. > e <- new.env() > class(e) [1] "environment" > class(e) <- c("foo", class(e)) > class(e) [1] "foo" "environment" > str(e) Classes 'foo', 'environment' length 0 <environment> > class(e) [1]

Hello, I want to use global variables in a package which is using a namespace. But I don`t know how to change the values of the global variables. I know how to get the value of the variables, e.g. > base::pi [1] 3.141593 but following code doesn`t work > base::pi <- 3.14 Error: Object "base" not found Thanks for your help, Thomas Stabla -- > version _ platform

Hello All, '\\' is printed as '\\', but it is actually only one character. Sometimes, I'd rather print it as a single '\'. Is there a function to do so in R? > nchar('\\') [1] 1 > print('\\') [1] "\\" -- Tom

the following is a trivialized version of some functional code i tried to use in r: (funcs = lapply(1:5, function(i) function() i)) # a list of no-parameter functions, each with its own closure environment, # each supposed to return the corresponding index when applied to no arguments sapply(funcs, function(func) func()) # supposed to return c(1,2,3,4,5) there is absolutely nothing unusual in
