Display name, class, size, and dimensions of each object in a given environment. Alternatively, if the main argument is a list-like object, its elements are listed and described.
ll(pos=1, unit="KB", digits=0, dim=FALSE, sort=FALSE, class=NULL, invert=FALSE, ...)
pos |
environment position number, environment name, data frame,
list, model, or any object that |
unit |
unit for displaying object size: "bytes", "KB", "MB", or first letter. |
digits |
number of decimals to display when rounding object size. |
dim |
whether object dimensions should be returned. |
sort |
whether elements should be sorted by name. |
class |
character vector for limiting the output to specified classes. |
