Browse Objects in Environment

Description

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

Usage

browseEnv(envir = .GlobalEnv, pattern,
          excludepatt = "^last\.warning",
          html = .Platform$OS.type != "mac",
          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 on non Macintosh machines to display the workspace on a HTML page in your favorite browser.
`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. Only allows one level of recursion into object structures. The HTML version is not dynamic.

It can be generalized. See sources (‘..../library/base/R/databrowser.R’) for details.

wsbrowser() is currently just an internally used function; its argument list will certainly change.

Most probably, this should rather work through using the ‘tkWidget’ package (from www.Bioconductor.org).

Examples

if(interactive()) {
   ## create some interesting objects :
   ofa <- ordered(4:1)
   ex1 <- expression(1+ 0:9)
   ex3 <- expression(u,v, 1+ 0:9)
   example(factor, echo = FALSE)
   example(table, echo = FALSE)
   example(ftable, echo = FALSE)
   example(lm, echo = FALSE)
   example(str, echo = FALSE)

   ## and browse them:
   browseEnv()

   ## a (simple) function's environment:
   af12 <- approxfun(1:2, 1:2, method = "const")
   browseEnv(envir = environment(af12))
 }
