| pos | an environment, a character string, or an integer value (or vector of integers). If envir is not provided, you can specify the value of pos for envir. |
| name | a character string or a name that corresponds to an environment or package from the search list (search()). |
| envir | an environment. A value specified in envir overrides values specified in name and pos. If you do not specify a value for envir, you can set it by passing the value for either name or pos to as.environment. |
| all.names | a logical value. If TRUE, all objects, including hidden objects, are listed. The default is FALSE. |
| pattern | a character vector. Specifies a valid regular expression. Only objects that match the regular expression are returned. |
| mode | a character string. Specifies the mode of the listed objects. Only objects that match the mode are returned. The default, "any", indicates that any mode is acceptable. |
| x | a ls.str object with the attribute "envir". |
| max.level | the maximal level of a nesting structure can be displayed. The default is 1. |
| give.attr | a logical value. If TRUE, the attributes of object and its subcomponents are shown. The default is FALSE. |
| digits | a positive integer number. The number of significant digits to print. |
| ... |
|
| ls.str | returns a vector of class "ls_str" containing the found object names, environment, and mode. |
| lsf.str | returns a vector of class "ls_str" containing the found object names, environment, and mode. |
| print.ls.str | calls str for each object. |
