What's the best object browser? Dear all, I have tried all the popular R IDE or editors like Eclipse, Komodo, JGR, Revolution... They all have fancy fucntions like auto completion, syntax highlight.... BUT, I JUST WANT A OBJECT BROWSER! The easiest way to view objects in R console is fix(), but you have no global view of all the objects in the workspace. Revolution has the best object browser so far, but this thing is way too big... Eclipse all has automatically object browser, but you can't only see the basic summary info. and it's really tricky to configure StatET. Jgr is very handy, when you double click the object name, you can view the object in a spreadsheet like using fix(), but you have to press the "Refresh" button each time you want to see the updated objects... So, is there any thing like the combination of eclipse and Jgr? If not, I am interested to develope something to fulfill this simple but very important function. But right now I have no idea where to start. Any suggestions?

Hi
I noticed that nobody answered your question yet so here is my try.
If you want to see what objects are in your environment you can use ls()
but its output is only names of objects. Here is a function I use a long
time for checking what objects are there, their type, size and possibly
rows columns. You can modify it to give you some more info but usually it
is not needed.
Regards
Petr
ls.objects <- function (pos = 1, pattern, order.by)
{
napply <- function(names, fn) sapply(names, function(x) fn(get(x,
pos = pos)))
names <- ls(pos = pos, pattern = pattern)
obj.class <- napply(names, function(x) as.character(class(x))[1])
obj.mode <- napply(names, mode)
obj.type <- ifelse(is.na(obj.class), obj.mode, obj.class)
obj.size <- napply(names, object.size)
obj.dim <- t(napply(names, function(x) as.numeric(dim(x))[1:2]))
vec <- is.na(obj.dim)[, 1] & (obj.type != "function")
obj.dim[vec, 1] <- napply(names, length)[vec]
out <- data.frame(obj.type, obj.size, obj.dim)
names(out) <- c("Type", "Size", "Rows",
"Columns")
if (!missing(order.by))
out <- out[order(out[[order.by]]), ]
out
}

I am not using it myself but it looks like there is an API for extensions and in addition Deducer works in many IDEs (if not all). I have in plan to write a tree like visual object inspector for ESS, but it will take some time. If you manage to start the project, try to keep in mind that "object browser" is actually an "environment inspector" so it could be used to inspect environments in an hierarchical fashion. Such approach would be useful during a debug session for instance. Also the same code might be potentially useful for inspection of S4/S3 class hierarchy, multilevel lists, proto hierarchies, Rjava, cpp or whatever object or collections with tree-likes structure. So generality is relay important here. Cheers, Vitally.> > Peter

If you hope to get an answer it would be a good idea to CC John Verzani, maintainer of gWidgets. Give RStudio a try as it comes with a built-in object browser.
