misplaced.data.frame

Indexes records whose relative positions would change if sorted, i.e. records that would not have the same nearest neighbors (before and after). unsorted() returns the records corresponding to this index.

Supports systematic scrutiny, modification, and integration of
data. The function status() counts rows that have missing values in
grouping columns (returned by na() ), have non-unique combinations of
grouping columns (returned by dup() ), and that are not locally sorted
(returned by unsorted() ). Functions enumerate() and itemize() give
sorted unique combinations of columns, with or without occurrence counts,
respectively. Function ignore() drops columns in x that are present in y,
and informative() drops columns in x that are entirely NA; constant() returns
values that are constant, given a key.  Data that have defined unique
combinations of grouping values behave more predictably during merge operations.
