Bimap-envirAPI: Environment-like API for Bimap objects

Description

These methods allow the user to manipulate any Bimap object as if it was an environment. This environment-like API is provided for backward compatibility with the traditional environment-based maps.

Usage

ls(name, pos = -1L, envir = as.environment(pos), all.names = FALSE, pattern, sorted = TRUE) exists(x, where, envir, frame, mode, inherits) get(x, pos, envir, mode, inherits) #x[[i]] #x$name


  ## Converting to a list mget(x, envir, mode, ifnotfound, inherits) eapply(env, FUN, ..., all.names, USE.NAMES) #contents(object, all.names)


  ## Additional convenience method sample(x, size, replace=FALSE, prob=NULL, ...)

Arguments

name
A Bimap object for ls. A key as a literal character string or a name (possibly backtick quoted) for x$name.
pos, all.names, USE.NAMES, where, frame, mode, inherits
Ignored.
envir
Ignored for ls. A Bimap object for mget, get and exists.
pattern
An optional regular expression. Only keys matching 'pattern' are returned.
x
The key(s) to search for for exists, get and mget. A Bimap object for [[ and x$name. A Bimap object or an environment for sample.
i
Single key specifying the map element to extract.
ifnotfound
A value to be used if the key is not found. Only NA is currently supported.
env
A Bimap object.
FUN
The function to be applied (see original eapply for environments for the details).
...
Optional arguments to FUN.
size
Non-negative integer giving the number of map elements to choose.
replace
Should sampling be with replacement?
prob
A vector of probability weights for obtaining the elements of the map being sampled.
sorted
logical(1). When TRUE (default), return primary keys in sorted order.
