idiogram (version 1.46.0)

idiograb: idiograb

Description

idiograb reads the position of the graphics pointer when the (first) mouse button is pressed. idiogram also reads a second position of the graphics pointer after another mouse button press. The two points selected are used to define a diagonal line from which a bounding box will be constructed. It then retrieves the gene identifiers of the points that lie within the bounding box.

Usage

idiograb(idio, show.box = TRUE, brush = NULL, ...)

Arguments

idio
point coordinates and cooresponding gene identifiers from an idiogram function call
show.box
boolean. if TRUE, a box is drawn showing the selected region
brush
a color to highlight the points within the selected region
...
additional plotting paramters passed to points to modify the points within the selected region

Value

A character vector of gene identifiers

Details

Coordinates can be passed in a plotting structure (a list with x, y, and labels components). Typically this is generated from a call to idiogram. The points selected are used to define the top-left and bottom-right locations or the bottom-left and top-right locations for bounding box. These locations can be selected in any order. A character vector of the labels of all the points that lie within the selected region is returned.
