Select an area in the heatmap

1 2	selectArea(ht_list, pos1 = NULL, pos2 = NULL, mark = TRUE, verbose = TRUE, ht_pos = NULL)

`ht_list`	A `HeatmapList-class` object returned by `draw,Heatmap-method` or `draw,HeatmapList-method`.
`mark`	Whether mark the selected area as a rectangle.
`pos1`	If the value is `NULL`, it can be selected by click on the heatmap (of cource, the heatmap should be on the interactive graphic device). If it is set, it must be a `unit` object with length two which corresponds to the x and y position of the point.
`pos2`	Another point as `pos1`, together with `pos1` defines the selected region.
`verbose`	Whether to print messages.
`ht_pos`	A value returned by `ht_pos_on_device`.

The regions can be selected interactively or manually by setting pos1 and pos2.

A DataFrame object with row indices and column indices corresponding to the selected region.
