Clears the log contents up to
a given offset or bookmark. Default: clear the entire log.
When x is NULL, the global inlabru log is updated, and invisible(NULL)
is returned. Otherwise the updated object is returned (invisibly).
Returns (invisibly) the modified bru_log object, or NULL (when x is NULL)
Arguments
x
A bru_log object, or in some cases, and object that can be
converted/extracted to a bru_log object. NULL denotes the global
inlabru log object.
bookmark
character; The label for a bookmark with a stored offset.
offset
integer; a position offset in the log, with 0L pointing at
the start of the log. If negative, denotes the point abs(offset) elements
from tail of the log. When bookmark is non-NULL, the offset applies a
shift (forwards or backwards) to the bookmark list.
