Browse Objects in Environment

The browseEnv function opens a browser with list of objects currently in sys.frame() environment.

Keywords
interface
Usage
browseEnv(envir = .GlobalEnv, pattern,
          excludepatt = "^last\\.warning",
          html = .Platform$GUI != "AQUA",
          expanded = TRUE, properties = NULL,
          main = NULL, debugMe = FALSE)
Arguments
envir

an environment the objects of which are to be browsed.

pattern

a regular expression for object subselection is passed to the internal ls() call.

excludepatt

a regular expression for dropping objects with matching names.

html

is used to display the workspace on a HTML page in your favorite browser. The default except when running from R.app on macOS.

expanded

whether to show one level of recursion. It can be useful to switch it to FALSE if your workspace is large. This option is ignored if html is set to FALSE.

properties

a named list of global properties (of the objects chosen) to be showed in the browser; when NULL (as per default), user, date, and machine information is used.

main

a title string to be used in the browser; when NULL (as per default) a title is constructed.

debugMe

logical switch; if true, some diagnostic output is produced.

Details

Very experimental code: displays a static HTML page on all platforms except R.app on macOS.

Only allows one level of recursion into object structures.

It can be generalized. See sources for details. Most probably, this should rather work through using the tkWidget package (from https://www.bioconductor.org).
