Hello there, any ideas on how to save all the objects on my workspace inside a list object? For example, say my workspace is as follows ls() [1] "x" "y" "z" and suppose I want to put these objects inside a list object, say object.list <- list() without having to explicitly write down their names as in object.list$x = x object.list$y = y object.list$z = z Is this possible? Thanks in advance, Eduardo Horta [[alternative HTML version deleted]]
Try this: sapply(ls(pattern = "x|y|z"), get, simplify = F) On Mon, Jan 3, 2011 at 3:25 PM, Eduardo de Oliveira Horta < eduardo.oliveirahorta@gmail.com> wrote:> Hello there, > > any ideas on how to save all the objects on my workspace inside a list > object? > > For example, say my workspace is as follows > ls() > [1] "x" "y" "z" > > and suppose I want to put these objects inside a list object, say > > object.list <- list() > > without having to explicitly write down their names as in > > object.list$x = x > object.list$y = y > object.list$z = z > > Is this possible? > > Thanks in advance, > > Eduardo Horta > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >-- Henrique Dallazuanna Curitiba-Paraná-Brasil 25° 25' 40" S 49° 16' 22" O [[alternative HTML version deleted]]

Eduardo,
Try this:
object.list <- sapply(objects(), function(x) get(x), simplify=F,
USE.NAMES=T)

[R] Saving objects inside a list
Sent by:

Hello there,
any ideas on how to save all the objects on my workspace inside a list
object?
For example, say my workspace is as follows
ls()
[1] "x" "y" "z"
and suppose I want to put these objects inside a list object, say
object.list <- list()
without having to explicitly write down their names as in
object.list$x = x
object.list$y = y
object.list$z = z
Is this possible?
Thanks in advance,
Eduardo Horta

On my machine they produce a list but in "reverse order" compared to the result of ls(),...maybe it's the same with you : names(as.list(.GlobalEnv))[6] is the name of the 6th variable FROM THE END of ls().

Hello, I've contacted the guys from RKWard. Below I paste the answer Thomas Friedrichsmeier gave me. ------- Hi, the problem appears to be our use of "active bindings" (see ?makeActiveBinding). Internally, RKWard replaces all objects inside .GlobalEnv by active bindings. This allows us to find out, when the objects get modified. For almost all purposes, these active bindings behave just like the regular object, but apparently, as.list() copies the accessor functions, instead. I do wonder whether that is the expected behavior of as.list()... Either way, RKWard will probably switch to a different strategy for detecting when objects get modified, in the not-too-distant future. The problem should go away, then. Meanwhile, perhaps you can work around the problem using code like this: oblist <- sapply (ls (all.names=TRUE), function (x) get (x), simplify=FALSE) Regards Thomas On Tue, Jan 4, 2011 at 2:54 PM, William Dunlap <wdunlap@tibco.com> wrote:> Under RKWard, do you get (at the command line) > > environment() > <environment: R_GlobalEnv> > If environment() doesn't evaluate to .GlobalEnv's > value then > as.list(environment()) > may show the B=1000.
