Usage
## S3 method for class 'default}(pattern=".*", ..., private=FALSE, properties=getOption("R.oo::ll/properties"), sortBy=NULL, envir=parent.frame())':
llundefined
- pattern
{Regular expression pattern specifying which members to
return. If ".*", all names are matched.}
- ...
{A named vector of format functionName=value, where
functionName() will be called on each member found. If the
result matches the value, the member is returned, otherwise
not.}
- private
{If TRUE, also private members, i.e. members with
a name starting with a . (period), will be listed, otherwise not.}
- properties
{Names of properties to be returned. There must exist
a function with the same name, because it will be called. This way
one can extract any type of property by defining new methods.}
- sortBy
{Name or index of column (property) to be sorted by.
If NULL, the objects are listed in the order they are found.}
- envir
{An environment, a search path index or a name of a package
to be scanned.}
Returns a data.frame containing information about all the members.
Default properties returned{
It is possible to set the default value of argument properties
by setting option "R.oo::ll/properties", e.g.
options("R.oo::ll/properties"=c("data.class", "dimension")).
If this option is not set when the package is loaded, it is set to
c("data.class", "dimension", "objectSize").
}
To list all objects in .GlobalEnv:

To list all functions in the methods package:
ll(mode="function", envir="methods")
To list all numeric and character object in the base package:
ll(mode=c("numeric", "character"), envir="base")
To list all objects in the base package greater than 40kb:
subset(ll(envir="base"), objectSize > 40000)
[object Object]
ll.Object().
