get_slice_edgelist.RdFilter edgelist for a time slice
get_slice_edgelist( edge.list, select_cols = NULL, start_time, end_time = NULL, duration = NULL, index = FALSE, as_date = NULL )
| edge.list | the edgelist from which to compute the time slices |
|---|---|
| select_cols | optional vector of 3 (2 for multi-graphs) elements
specifying which columns are the source,target, and attributes from which
building the graph. Otherwise Column 1 is assumed to be the source, column
2 the target, column 3 the attribute. In the case of multi-graphs, the
third element is not needed and the number of edges between each pair of
vertices is computed according to ' |
| start_time | the timestamp a which start the timewindow slice. It can be an integer defining either the index of the start point or the unit of time at which to cut, or a datestring string. |
| end_time | (optional) the timestamp a which to end the timewindow slice. It can be an integer defining either the index of the end point or the unit of time at which to cut, or a datestring string. |
| duration | (optional) the duration of the timewindow. If `end_time` is not provided it defines how long after `start_time` the window should be cut. |
| index | boolean, set to TRUE if start_time and end_time are supplied as indices. Defaults to FALSE. |
| as_date | (optional) boolean, are the timestamps supplied as datestrings? |
a tibble with the edgelist cut such that timestamps are between `start_time` and `end_time`
