Usage
browseEnv(envir = .GlobalEnv, pattern,
excludepatt = "^last\\.warning",
html = .Platform$GUI != "AQUA",
expanded = TRUE, properties = NULL,
main = NULL, debugMe = FALSE)Arguments
- envir
an
environmentthe 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.appon macOS.- expanded
whether to show one level of recursion. It can be useful to switch it to
FALSEif your workspace is large. This option is ignored ifhtmlis set toFALSE.- 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).

Examples
library(utils)
# NOT RUN {
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))
}
