objip

loop through all attached directories looking for pattern, possibly restricting to specified class or mode.

Description

Loop objects() through all attached directories (items in the search() list) looking for a regular expression pattern.

Usage

objip(pattern, where = search(), all.names=FALSE, mode="any", class,
      ls.function=if (mode != "any" || !missing(class)) "ls.str" else "ls")

Arguments

`pattern`	Character string containing a regular expression that is used to list only a subset of the objects. Only names matching 'pattern' are returned.
`where`	an object defining a database in the search list.
`all.names`	In R, a logical that is passed to the `ls` function. If 'TRUE', all object names are returned. If 'FALSE', names which begin with a '.' are omitted.
`mode, class`	See `ls.str` and `mode` for storage mode of an object. See `class` for object classes.
`ls.function`	Either `ls` or `ls.str`. If either `mode` or `class` is specified then the default is `ls.str`. If neither is specified then the default is `ls`.

Value

A list of 0 or more character vectors. Each character vector has the name of one of the items in the search() list. Each character vector contains the names of the objects in the specified environment which match the pattern. If there are no matching names in an environment, then the corresponding character vector is removed from the result.
