Re: [R] How to list R object properties & save workspace?
Hi Matej, You can also try: sapply(ls(), function(x) object.size(get(x))) or eapply(.GlobalEnv, object.size) which list all objects - as with ls() - but giving their sizes. I'm also quite new to R so am not sure which other properties you could hope to get out of it, but by substituting another command for the "object.size" command - e.g. "str" or "summary" - you can get other information out of it for every object: with "str", a similar and perhaps identical output to what Duncan Murdoch suggested with ls.str(). You could try looking up the str() function and see if there are properties that you are interested in. E.g. sapply(ls(), function(x) str(get(x), give.length = TRUE)) which lists everything with length as [1:...]. You could also look at: browseEnv(envir = .GlobalEnv, properties = NULL) Guy Matej Kovacic wrote: > > Hi, > I am new to R and have a couple of questions. > > I know how to list all objects (with ls()), but how to list all > properties of them? > > For instance, I found function object.size(), but I would also like to > know whether one object is a dataset or just one vector (variable) or > even only one value, etc... > > And another question - how to save workspace to a custom location while > running R?

I know how to list all objects (with ls()), but how to list all properties of them? ls.str() gives more info than ls(). str() on a particular one gives more detail. For instance, I found function object.size(), but I would also like to know whether one object is a dataset or just one vector (variable) or even only one value, etc... And another question - how to save workspace to a custom location while running R? Is there any command for that? save.image(file="mycustomlocation") Duncan Murdoch __ 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.

Is there any command for that? > You could use JGR to display a list similar to what you described (via "Object browser"), and to graphically save the workspace to a custom location. JGR is a cross-platform R GUI that is more advanced than the default GUI/terminal. Alternatively, you can save the workspace wherever you want via save.image().
