        dimensions=FALSE,function.dim="", ...)
## S3 method for class 'data.frame':
ll(pos, ...)
## S3 method for class 'list':
ll(pos, ...)

Arguments

pos environment position number, environment name, list, or data frame.
unit required unit for displaying object size: "KB", "MB", "bytes", or first letter.
digits number of decimals to display when rounding object size.
dimensions whether object dimensions should be returned.
function.dim value to report as the dimension of function objects.

Details

A verbose alternative to ls().

Value

A data frame with named rows and the following columns:

Class object class.
KB object size (see notes).

Note

The name of the object size column is the same as the unit used.

Objects of class classRepresentation, ClassUnionRepresentation, and grob do not have a defined size, so 0 bytes are assumed for those.
