mark	Whether to mark the selected position as a point.
pos	If the value is NULL, it can be selected by click on the heatmap (of cource, the heatmap should be on the interactive graphics 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.

Value

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

Examples

if(dev.interactive()) {
    m = matrix(rnorm(100), 10)
    rownames(m) = 1:10
    colnames(m) = 1:10

    ht = Heatmap(m)
    ht = draw(ht)
    selectPosition(ht)
