%description
Provides feedback about 'data.table' operations. 'dtlog' redefines the
subsetting method for data tables as well as several functions exported by
'data.table' so that each operation prints a short message describing what
it did: how many rows were removed, which columns were added, updated or
dropped, how many groups an aggregation produced, and so on. The
operations themselves are left untouched, including modification by
reference. It also provides dttable(), which describes the variables a
single data table holds and passes every other call on to base::table()
unchanged. Inspired by the 'tidylog' package.
