If gvarbrowser isn't quite to your liking, it isn't so hard to build your own variable browser. This uses a slight modification of Petr's function and wraps in a gWidgets interface. Modify his function to display what info you want and add a handler to the tbl object to have some action associated with a user selection:
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(names, obj.type, obj.size, stringsAsFactors=FALSE)#, obj.dim) names(out) <- c("Name", "Type", "Size")#, "Rows", "Columns") if (!missing(order.by)) out <- out[order(out[[order.by]]), ] out } library(gWidgets) options(guiToolkit="RGtk2") w <- gwindow() g <- ggroup(cont=w, horizontal=FALSE) bg <- ggroup(cont=g) glabel("Pattern:", cont=bg) flt <- gedit("", cont=bg, expand=TRUE) tbl <- gtable(ls.objects(), cont=g, expand=TRUE) bg <- ggroup(cont=g) addSpring(bg) ref <- gbutton("refresh", cont=bg) update_gui <- function(...) { pat <- svalue(flt) tbl[] <- ls.objects(pattern=pat) TRUE # for task callback } lapply(list(flt, ref), addHandlerChanged, handler=update_gui) This will refresh when the user updates the pattern to filter by or the refresh button. One can have it refresh when the global environment changes by adding a task callback: addTaskCallback(update_gui) But this can slow things up if the workspace is large. The RStudio object browser has a very fast way to see if there are changes to the objects it is monitoring but this is done in C++ code. -- View this message in context: http://r.789695.n4.nabble.com/Object-Browser-tp2594912p4650575.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
