[Rd] Correction to documentation of print.ls_str in utils package

[Brian Diggs]

In the documentation for print.ls_str (on the ls.str page) in the utils package, the description for max.level is not correct.  It says "Default 0: Display all nesting levels."  The default, according to the Usage on that page and the source code, is 1. Also, a value of 0 does not display all the nesting levels; NA does that (based on the documentation of str). A value of 0 does not display any nested levels. I recommend changing that sentence to "If NA, display all nesting levels. Default 1: Display only the first nested level."
