## 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$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).

### See Also

`str`, `ls`.

### 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, ask = 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))
     }
