A |
Returns a character string
of the text that the co-occurrence
counts were calculated against.
This comes from the corp_text
object used to create
the corp_cooccurrence
object.
Returns a data.table
of the tokenization that the co-occurrence
counts were calculated against.
This comes from the corp_text
object used to create
the corp_cooccurrence
object.
Returns a data.table
containing the co-occurrence counts.
Note that a data.table
is also a data.frame
so
if the data.table
library is not loaded the returned
object will behave exactly as a data.frame
; however,
for large data sets there will be significant performance
enhancement offered by exploiting data.table functionality.
The data.table
is of the form:
Classes ‘data.table’ and 'data.frame': ... $ x: chr $ y: chr $ H: int $ M: int - attr(*, "sorted")= chr "x" "y" - attr(*, ".internal.selfref")=<externalptr>
where H
is the number of times x
types
co-occurs with y
types (think Hits), and M
is the number of times x
types fail to co-occur with
y
types when they could have (think Misses);
hence H + M
is the maximum number of times
that x
types can co-occur with y
types.
