R: Functions to manage and explore the workspace

## Functions to manage and explore the workspace

### Description

These functions help you to find out what has gone wrong and to start afresh if needed.

### Usage

    lls(pos = 1, pat = "", all=FALSE, print=TRUE )
    clear()

### Arguments

`pos` | Numeric. What position in the search path do you want listed.
`pat` | Character. List only objects that have this string in their name.
`all` | Logical. Should invisible objects be printed too - see `ls` to which this argument is passed.
`print` | Logical. Should the result be printed?

### Details

`lls` is designed to give a quick overview of the name, mode, class and dimension of the object in your workspace. They may not always be what you think they are.

`clear` clears all your objects from workspace, and all attached objects too — it only leaves the loaded packages in the search path; thus allowing a fresh start without closing and restarting R.

### Value

`lls` returns a data frame with four character variables: codename, codemode, codeclass and codesize and one row per object in the workspace (if `pos=1`). `size` is either the length or the dimension of the object. The data frame is by default printed with left-justified columns.

### Author(s)

`lls`: Unknown. Modified by Bendix Carstensen from a long forgotten snatch.

`clear`: Michael Hills / David Clayton.

### Examples

    x <- 1:10
    y <- rbinom(10, 1, 0.5)
    m1 <- glm( y ~ x, family=binomial )
    M <- matrix( 1:20, 4, 5 )
    .M <- M
    dfr <- data.frame(x,y)
    attach( dfr )
    lls()
    search()
    clear()
    search()
    lls()
    lls(all=TRUE)
