Functions to manage and explore the workspace
These functions help you to find out what has gone wrong and to start afresh if needed.
lls(pos = 1, pat = "", all=FALSE, print=TRUE ) clear()
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 |
print |
Logical. Should the result be printed? |
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.
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.

forgotten snatch.
